The catalytic decarboxylation of aromatic carboxylic acids provides an alternative route to generate aryl metal species in situ without using organometallic compounds. Herein, a cationic iridium-catalyzed through CO2 extrusion is described. substrate scope broad, and the reaction proceeds even presence various functional groups. Additionally, potential utility was demonstrated decarboxylative h...

Reaction of aryl methyl ketone with isatin in the presence of a base afforded 2- arylquinoline-4-carboxylic acid (3). Reaction of diazomethane with compound 3 yielded the ester 4. Compound 5 was prepared from the reaction of N, N'-dialkylethyl (or propyl) arnine with 4. Addition of hydrazine hydrate to compound 4a gave 2- (2- pyridyl) quinoline-4-carboxylic acid hydrazide (6). Reaction of l...

The development of graphene oxide/rare earth complexes luminescent materials is limited due to the strong quenching ability oxide. However, hybrid with pyromellitic acid (PMA) as ligand not only have better performance, but also stronger luminescence intensity. Herein we tested effect carboxylic structure PMA on intensity materials. Phthalic (PA), Isophthalic (i-PA) and Terephthalic (p-PA) are ...

Progress in DNA-encoded chemical library synthesis and screening crucially relies on the availability of DNA-compatible reactions, which proceed with high yields excellent purity for a large number possible building blocks. In past, experimental conditions have been presented execution Suzuki Sonogashira cross-coupling reactions on-DNA. this article, our aim was to optimize comparing results pr...

The Baeyer–Villiger oxidation (BVO) of ketone and aldehyde can produce ester formate, which both have wide applications in many areas. In this work, a series Sn-containing silicates were prepared through the sol-gel process by using structure-directing crystallizing agents post-synthetic coordinated modification binaphthol. Characterizations revealed that loading (L)-sodium lactate as agent dec...
