The article 《Isolation of Carbene-Stabilized Arsenic Monophosphide [AsP] and its Radical Cation [AsP]+• and Dication [AsP]2+》 in relation to this compound, is published in Chemistry – A European Journal. Let’s take a look at the latest research on this compound (cas:141556-42-5).

Arsenic monophosphide (AsP) species supported by two different N-heterocyclic carbenes were prepared by reaction of (IDipp)PSiMe3 (1) (IDipp=1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) with (IMes)AsCl3 (2) (IMes=1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene) to afford the dichloride [(IMes)As(Cl)P(IDipp)]Cl (3), which upon reduction with KC8 furnished heteroleptic [(IMes)AsP(IDipp)] (4). The corresponding mono- and dications [(IMes)AsP(IDipp)][PF6], [5]PF6, and [(IMes)AsP(IDipp)][GaCl4]2, [6][GaCl4]2, resp., were prepared by one-electron oxidation of 4 with ferrocenium hexafluorophosphate, [Fc]PF6, or by chloride abstraction from 3 with two equivalent of GaCl3, resp. Compounds 4-6 represent rare examples of heterodiat. interpnictogen compounds, and X-ray crystal structure determinations together with d. functional theory (DFT) calculations reveal a consecutive shortening of the As-P bond lengths and increasing bond order, in agreement with the presence of an arsenic-phosphorus single bond in 4 and a double bond in 62+. The EPR signal of the cationic radical [5]+a. indicates a sym. spin distribution on the AsP moiety through strong hyperfine coupling with the 75As and 31P nuclei.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Tailor, Sanita B.; Manzotti, Mattia; Smith, Gavin J.; Davis, Sean A.; Bedford, Robin B. researched the compound: 2-Phenylpyridine( cas:1008-89-5 ).Safety of 2-Phenylpyridine.They published the article 《Cobalt-Catalyzed Coupling of Aryl Chlorides with Aryl Boron Esters Activated by Alkoxides》 about this compound( cas:1008-89-5 ) in ACS Catalysis. Keywords: biaryl preparation transmetalation key step kinetics linear free energy; aryl chloride boron reagent alkoxide Suzuki coupling cobalt catalyst. We’ll tell you more about this compound (cas:1008-89-5).

The cobalt-catalyzed Suzuki biaryl cross-coupling of aryl chloride substrates with aryl boron reagents, activated with more commonly used bases, remained a significant unmet challenge in the race to replace platinum group metal catalysts with Earth-abundant metal alternatives. This highly desirable process can be realized using alkoxide bases, provided the right counterion is employed, strict stoichiometric control of the base is maintained with respect to the aryl boron reagent, and the correct boron ester is selected. Potassium tert-butoxide works well, but any excess of the base first inhibits and then poisons the catalyst. Lithium tert-butoxide performs very poorly, while even catalytic amounts of lithium additives also poison the catalyst. Meanwhile, a neopentane diol-based boron ester is required for best performance. As well as delivering this sought-after transformation, a detailed mechanistic and computational investigations to probe the possible mechanism of the reaction has been discussed and explains the unexpected exptl. observations.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Blood-Brain Barrier Penetrating Luminescent Conjugates Based on Cyclometalated Platinum(II) Complexes, published in 2020-11-18, which mentions a compound: 1008-89-5, mainly applied to platinum phenylpyridine benzofuranylpyridine benzotiophenylpyridine imidazole derivative complex preparation luminescence; cytotoxicity platinum phenylpyridine benzofuranylpyridine benzotiophenylpyridine imidazole derivative, Name: 2-Phenylpyridine.

Herein we report on the synthesis, structural characterization and photophys. properties of cyclometalated Pt(II) complexes [Pt(N^C)(PPh2(C6H4COOH))Cl] (where N^C ligands are 2-phenylpyridine, (2-benzofuran-3-yl)pyridine, and (2-benzo[b]tiophen-3-yl)pyridine) and their conjugates with the histidine-containing RRRRRRRRRRHVLPKVQA peptide. This peptide contains the RHVLPKVQA sequence, which is responsible for antiamyloid activity, and the Arg9 RRRRRRRRR domain, which shows improved translocation through cell membranes. The chem. underpinning the conjugation is regioselective complexation between Pt(II) complexes and histidine residue in the peptide. The prepared conjugates have been characterized using high-resolution mass spectrometry and NMR spectroscopy. It was shown that the conjugates are easily soluble in aqueous media and display emission band profiles essentially similar to those of the starting complexes but considerably higher luminescence quantum yield and much longer phosphorescence lifetime. MTT assay on HeLa cell culture revealed no cytotoxicity up to 10μM after 24 h of incubation. Ex vivo and in vivo neuroimaging experiments on both wild and amyloid peptide expressing strains of Drosophila melanogaster revealed that the conjugates penetrate the blood-brain barrier and are evenly distributed throughout the brain independently of the strain used.

Author is Wu, Jason Hongliu; Radinov, Rumen; Porter, Ned A..

The reaction of the acrylamide derived from the parent achiral oxazolidinone, I, with alkyl iodides (R-I), and allyltributylstannane has been investigated. The free radical reaction is promoted by Lewis acids such that clean conversion to the (1:1:1, R:I:allyl) adduct II, takes place in low temperature reactions initiated with triethylborane. In the presence of zinc triflate and chiral bis(oxazolines), III, derived from amino alcs., excellent yields of the (1:1:1) adduct are formed. Furthermore, this adduct is formed with good to excellent enantioselectivity. A model is suggested involving an intermediate complex of the radical, zinc ion, and the chiral ligand. The product is hydrolyzed and methylated to give the corresponding Me ester and the configuration of this ester is determined to be S if the bis(oxazoline) has the S,S configuration.

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:29046-78-4) here.

A mechanistically unique functionalization strategy for a benzylic C(sp3)-H bond was developed based on facile oxidation event of indole substrates. This novel pathway was initiated by efficient radical generation at benzylic position of substrate, with subsequent transition metal catalysis to complete overall transformation. Ultimately, an aryl or an acyl group could be effectively delivered from an aryl (pseudo)halide or an acid anhydride coupling partner, resp. The developed method utilized mild conditions and exhibited a wide substrate scope for both substituted indoles and C(sp2)-based reaction counterparts. Mechanistic studies showed that competitive hydrogen atom transfer (HAT) processes, which were frequently encountered in conventional methods, are not involved in the product formation process of the developed strategy.

Structure-activity relationships were discussed, leading to the identification of compounds F8 (IC50 = 0.28 μM against HGC-27 cell) and T9 (IC50 = 1.84 μM against HGC-27 cell) with improved cytotoxicity, anti-gastric cancer proliferation potency, induction of cell apoptosis and cell cycle arrest ability, inhibition of cell migration and invasion. What is worth mentioning is that compound F8 was more efficient and less toxic than the pos. drug capecitabine in vivo on the HGC-27-xenograft model. Meanwhile, compound F8 exhibited suitable pharmacokinetic properties and less acute toxicity (LD50 > 1000 mg/kg). Besides, western blotting anal., IHC anal., differentially expressed proteins anal. and ABPP experiment indicated that compound F8 could modulate mol. pathways involved in apoptosis and cell cycle progression. Consequently, compound F8 is a strong candidate for the development of human gastric cancer therapy.
