Abstract
A visible-light-promoted radical cascade reaction of N-arylacrylamide and cyclobutanone oxime esters with sulfur dioxide insertion is established. Mainly through the exploration of the visible light wavelength, it is found that the light source has a certain influence on the formation of cyanoalkylsulfonylated oxindoles, furnishing a range of sulfones in good to excellent yields. This protocol presents good functional group compatibility and does not require transition metals, photosensitizers, external bases, or oxidants.

Abstract
A mild and efficient visible-light-induced radical difluoromethylation/cyclization of unactivated alkenes toward the synthesis of substituted quinazolinones with easily accessible difluoromethyltriphenylphosphonium bromide has been developed. The transformation has the advantages of wide functional group compatibility, a broad substrate scope, and operational simplicity. The benign protocol offers a facile access to pharmaceutically valuable difluoromethylated polycyclic quinazolinones.
