Metal-Free Oxidative Cross Esterification of Alcohols via Acyl Chloride Formation

A novel metal-free oxidative cross esterification of alcohols has been achieved using trichloroisocyanuric acid as an oxidant. The alcohols were converted in situ into their corresponding acyl chlorides, which were then reacted with primary and secondary aliphatic, benzylic and allylic alcohols and phenols. A wide variety of esters was obtained in satisfactory yields.

From ketones to esters by a Cu-catalyzed highly selective C(CO)-C(alkyl) bond cleavage: Aerobic oxidation and oxygenation with air

The Cu-catalyzed aerobic oxidative esterification of simple ketones via C-C bond cleavage has been developed. Varieties of common ketones, even inactive aryl long-chain alkyl ketones, are selectively converted into esters. The reaction tolerates a wide range of alcohols, including primary and secondary alcohols, chiral alcohols with retention of the configuration, electron-deficient phenols, as well as various natural alcohols. The usage of inexpensive copper catalyst, broad substrate scope, and neutral and open air conditions make this protocol very practical. 18O labeling experiments reveal that oxygenation occurs during this transformation. Preliminary mechanism studies indicate that two novel pathways are mainly involved in this process. (Chemical Equation Presented)

Suzuki-miyaura coupling of NHC-Boranes: A new addition to the C-C coupling toolbox

Complexes of triaryl- and trialkylboranes with N-heterocyclic carbenes (NHCs) participate In Suzuki-Miyaura cross-coupling reactions and provide coupled products In good yields under base-free conditions. The reaction can be applied to Csp2-Csp
