摘要
An electrochemical method for the decarboxylative silylationof alpha,beta-unsaturated carboxylic acids was developed. A varietyof alkenylsilanes could be obtained in satisfactory yields and excellentselectivities under external oxidant- and metal-free conditions. Mechanisticstudies showed that the formation of the silyl radical was mediatedby NHPI, which produces the hydrogen atom transfer (HAT) reagent phthalimide N-oxyl (PINO) via multiple-site concerted proton-electrontransfer (MS-CPET).
