Photolysis of diazocyclopentadiene in alkyl sulphides. Formation of sulphonium cyclopentadienylides
Abstract
Photolysis of diazocyclopentadiene in the presence of dimethyl, diethy, and tetramethylene sulphides gave the corresponding sulphonium cyclopentadienylide; the ylide from di-t-butyl sulphide was unstable, and the reaction mixture gave the C–H and C–S insertion product from cyclopentadienylidene and the olefin elimination product.
