Alkene homologation via visible light promoted hydrophosphination using triphenylphosphonium triflate?
Chemical Communications Pub Date: 2020-12-09 DOI: 10.1039/D0CC07025D
Abstract
A hydrophosphination reaction of alkenes with triphenylphosphonium triflate under photocatalytic conditions is described. The reaction is promoted by naphthalene-fused N-acylbenzimidazole and is believed to proceed through intermediate formation of a phosphinyl radical cation. The resulting phosphonium salts are directly involved in the Wittig reaction leading to homologated alkenes.
