Photoelectrocatalytic bromolactonization with NaBr as the bromine source coupled with hydrogen evolution

Abstract

We report a mild and efficient photoelectrochemical (PEC) synthetic strategy for the construction of isobenzofuranone skeletons via bromolactonization using NaBr as the bromine source. This transformation proceeds in the absence of exogenous oxidants and additional catalysts, delivering the target products with isolated yields up to 98%.
