Series of highly polar stilbene (1a-e), diphenylbutadiene (2a-c) and phenylethenyIthiophene (3a-c) derivatives were prepared via Horner-Wadsworth-Emmons method with a view to produce new and efficient materials for second harmonic generation (SHG) in the solid-state. The single-crystal X-ray structures of compounds 1-3 reveal extensive polymorphism and a peculiar photodimerization of the 2-chloro-3,4-dimethoxy-4′-nitrostilbene derivative 1a to afford two polymorphs of tetra-aryl cyclobutane 4. The stilbene congeners 2-chloro-3,4-dimethoxy-4′-nitrostilbene (1a. non-centro), 5-bromo-2-hydroxy-3-nitro-4′-nitrostilbene (1b) and 4-dimethylamino-4′-nitrostilbene (1e), as well as 4′-fIuoro-4 ”-nitro-1,4-diphenyl-1,3-butadiene (2a) present the ideal, non-centrosymmetric arrangement of the chromophores for nonlinear optical (NLO) activity. Compounds lb and 2a exhibit only relatively Low intensity for second harmonic generation (0.04 and 0.18 times that of urea reference, respectively), while the stilbene polymorph 1a.non-centro shows NLO activity of over 32 times that of urea. In addition, the conjugated diaromatic compounds 1-3 display fluorescence behaviour in CH2Cl2 solutions with the exception of stilbene derivative 1b.

The CAS is 98-17-9. Through research, I have a further understanding and discovery of 3-(Trifluoromethyl)phenol

The competition between an unprecedented reductive chlorination and the Pummerer reaction was studied and applied to the synthesis of benzofused oxygen heterocycles including 3-aminochromanes and in the intramolecular chlorination of activated aromatic rings. The use of (COCl)(2) as a Pummerer activator showed substantial activity, producing alpha-chlorinated sulfides that can undergo Pummerer-Friedel-Crafts cyclization. If the aromatic ring has electron-donating groups in position three, then the reaction follows a different pathway, yielding the reductive chlorination products, where the chlorine atom comes from a sulfonium salt.

Computed Properties of C9H10O3. I found the field of Engineering; Environmental Sciences & Ecology very interesting. Saw the article Kinetics and Mass Yields of Aqueous Secondary Organic Aerosol from Highly Substituted Phenols Reacting with a Triplet Excited State published in 2021.0, Reprint Addresses Anastasio, C (corresponding author), Univ Calif Davis, Dept Land Air & Water Resources, Davis, CA 95616 USA.. The CAS is 120-14-9. Through research, I have a further understanding and discovery of 3,4-Dimethoxybenzaldehyde.

Biomass burning emits large amounts of phenols, which can partition into cloud/fog drops and aerosol liquid water (ALW) and react to form aqueous secondary organic aerosol (aqSOA). Triplet excited states of organic compounds (C-3*) are likely oxidants, but there are no rate constants with highly substituted phenols that have high Henry’s law constants (K-H) and are likely important in ALW. To address this gap, we investigated the kinetics of six highly substituted phenols with the triplet excited state of 3,4-dimethoxybenzaldehyde. Second-order rate constants at pH 2 are all fast, (2.6-4.6) x 10(9) M-1 s(-1), while values at pH 5 are 2-5 times smaller. Rate constants are reasonably described by a quantitative structure-activity relationship with phenol oxidation potentials, allowing rate constants of other phenols to be predicted. Triplet-phenol kinetics are unaffected by ammonium sulfate, sodium chloride, galactose (a biomass-burning sugar), or Fe(III). In contrast, ammonium nitrate increases the rate of phenol loss by making hydroxyl radicals, while Cu(II) inhibits phenol decay. Mass yields of aqueous SOA from triplet reactions are large and range from 59 to 99%. Calculations using our data along with previous oxidant measurements indicate that phenols with high KH can be an important source of aqSOA in ALW, with 3C* typically the dominant oxidant.

Twenty derivatives of chalcones were synthesized and their anticancer activities were estimated against both breast and liver cancer besides two human normal cell lines. Out of our candidates, there were five compounds 3 b, 3 d, 3 h, 7 and 10 b that revealed a broad superlative antitumor activity against both HepG2 and MCF7 cell lines. Surprisingly, 3 h showed the most powerful anticancer activity (GI(50)=5.43 +/- 0.170 mu M for MCF7 and GI(50)=1.80 +/- 0.50 mu M for HepG2) and displayed the most effective inhibition activity on tubulin with IC50=4.51 +/- 0.13 mu M. 3 h exerted low toxicity toward both normal human, Hs371.T and AML12, cell lines. 3 h revealed arrest of cell cycle at G2/M and induced apoptosis compared to control cells. Docking study of all newly derivatives was achieved to decide the preeminent binding mode. Generally, the outcome of the docking study showed that 3 h had better binding mode.

o-Alkenylation of unprotected phenols has been developed by direct C-H functionalization catalyzed by PdII. This work features phenol group as a directing group and realizes highly site-selective C-H bond functionalization of phenols to achieve the corresponding products in moderate to excellent yields at 60 degrees C. The advantages of this reaction include unprecedented C-H functionalization using phenol as a directing group, high regioselectivity, good substrate scope, mild reaction conditions, and high efficiency. To the best of our knowledge, this is the first example of a regioselective C-H alkenylation of unprotected phenols utilizing phenolic hydroxyl group as a directing group. The alkenylation of unprotected tyrosine and intramolecular cyclization are also successfully carried out under this catalytic system in good yields. Furthermore, this novel method enables a late-stage modification of complex phenol-containing bioactive molecules toward a diversity-oriented drug discovery.
