Sequence-controlled polymerization is the forefront of polymer chemistry. Herein, the feasibility of sequence regulation by using organocatalyzed ring-opening polymerization (ROP) is demonstrated. In particular, ring expansion strategy is employed to synthesize pre-organized monomers 1 and 2. ROP is conducted by using 1,5,7-triazabicyclo[4.4.0]dec-5-ene and benzyl alcohol as the catalyst and initiator, respectively. Poly(ester amide)s (PEAs) P1-P3 comprising glycolic acid, lactic acid, and 7-aminoheptanoic acid units are obtained in high molecular weights and good yields. NMR and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry results verify the microstructural integrity of P1 and P2. Differential scanning calorimetry results show that PEA without methyl branches is crystalline. Moreover, thermal stability, surface wettability, and degradation profiles of P1-P3 are also investigated.

Synthesis and characterization of novel coumarins containing carborane units were described. The breakdown reactions of cyclic oxonium derivatives of cobalt bis (1,2-dicarbollide) and closo-dodecaborate anions with a series of 7-hydroxy-3-substituted coumarins led to conjugates attached via C-7 position of the coumarin unit. The corresponding reactions of cobalt bis (1,2-dicarbollide) anion with 3-(4-hydroxybenzoyl)-7-methoxy-2H-chromen-2-one led to conjugates attached via C-3 position. Novel conjugates were isolated in the form of alkali metal salts. Therefore, these conjugates are of interest for the fluorescent study in aqua media. (C) 2020 Elsevier B.V. All rights reserved.

An economical and efficient method has been developed for the production of dibarbiturates of oxindole and arylidene barbituric acid derivatives via condensation of of isatin/aryl aldehyde with barbituric acid, through irradiation of visible light. Under the similar conditions 2 molecules of barbituric acid react with 1 molecule of isatin while only 1 molecule of barbituric acid reacts with 1 molecule of aldehyde. This transformation involves catalyst free pathway for the formation of desired products under mild reaction conditions. Metal free reaction conditions, high yield of products along with the absence of side-products are additional green features of this protocol.

Two copper(II) complexes with benzotriazole-based ligands having pyridyl and quinolinyl arms were synthesized in good yields and characterized fully via spectroscopic and crystallographic techniques. The crystal structures of the complexes revealed different coordination environments around copper(II) centers. The difference in structure was due to the steric effect of the ligands, which resulted in an octahedral and a square pyramidal geometry of the resulting complexes in the solid state. Both the air-stable complexes were utilized as precatalysts in catalytic click reactions and A(3) coupling.

Polymeric graphitic carbon nitride (g-C3N4) supported CuBr2 hybrid material (CuBr2@g-C3N4) was developed by impregnation of CuBr2 on g-C3N4 sheets. The morphology and physiochemical properties were analyzed by powder XRD, SEM, and HRTEM studies. The hybrid CuBr2@g-C3N4 material showed excellent selectivity in the aerobic oxidation of primary/secondary alcohols and benzoins to the corresponding carbonyl compounds in absence of any oxidizing agents. Further, CuBr2@g-C3N4 demonstrated direct oxidation of toluene derivatives to corresponding aldehydes in excellent yields. The g-C3N4 support provides excellent stability and heterogeneity to CuBr2 and was recovered simply by filtration and reused for ten times without appreciable loss in catalytic activity.

Here we present a comprehensive study on the [3+2]-cycloaddition of thiocarbonyl ylides with a wide variety of alkenes and alkynes. The obtained dihydro- and tetrahydrothiophene products serve as exceptionally versatile intermediates providing access to thiophenes, dienes, dendralenes, and vic-quarternary carbon centers. The use of high-pressure conditions enables thermally unstable, sterically encumbered or moderately reactive substrates to undergo the cycloaddition under mild conditions, thereby increasing the yield by up to 58%. In addition, we showcase its utility by the formal syntheses of the pharmaceuticals NGB 4420 and tenilapine.

In the presence of [p-cymene)RuCl2](2), (E)-configured alkenyl bromides couple with aromatic carboxylates to form orthovinylbenzoic acids. This C-H vinylation proceeds in high yields without any activating phosphine ligands and has an excellent functional group tolerance. Starting from commonly available (E/Z)-mixtures of alkenyl bromides, (E)-configured vinyl arenes or dienes are formed exclusively. Mechanistic studies show that this selectivity is achieved because the (E)configured alkenyl bromides undergo a smooth coupling, whereas the (Z)-isomers are rapidly eliminated with the formation of alkynes.
