Cercosporin-bioinspired selective photooxidation reactions under mild conditions

The development of an efficient system for selective oxidation of organic compounds to generate more valuable compounds with molecular oxygen is a significant challenge in industrial chemistry. Bioinspired by the ability of naturally occurring perylenequinonoid pigments (PQPs) to generate reactive oxygen species (ROS) upon photoirradiation, here we report that cercosporin, one of the perylenequinonoid pigments, can function as a cost-effective and environmentally friendly photocatalyst for a wide range of selective oxidations, including benzylic C-H bonds to carbonyls, amines to aldehydes, and sulfides to sulfoxides. All of the representative reactions proceeded smoothly with high efficiency under mild conditions. Owing to the use of inexpensive metal-free visible light-driven photocatalyst produced from microbial fermentation with cheap glucose as the starting material and the ease of handling, we expect that this developed method will be particularly attractive for many more applications in synthetic transformation.

Direct synthesis of aryl ketones by palladium-catalyzed desulfinative addition of sodium sulfinates to nitriles

Mild yet direct: A convenient and efficient method for the synthesis of various aryl ketones by palladium-catalyzed desulfinative addition of aromatic sulfinic acid sodium salts to various nitriles is described (see scheme). Aromatic and aliphatic nitriles are successfully reacted with arenesulfinic acid sodium salts to form aryl ketones in good yields.

Palladium-imidazolium-catalyzed carbonylative coupling of aryl diazonium ions and aryl boronic acids

Palladium(II) acetate and N,N-bis-(2,6-diisopropylphenyl)dihydroimidazolium chloride (2 mol%) were used to catalyze the carbonylative coupling of aryl diazonium tetrafluoroborate salts and aryl boronic acids to form aryl ketones. Optimal conditions includ

Ring tert-butylation of benzophenones and benzaldehyde with tert-butyllithium and thionyl chloride

One-flask ring tert-butylation of benzophenones and benzaldehyde with tert-butyllithium and thionyl chloride is reported. The scope of the reaction and the suggested mechanism are discussed.
