A novel intramolecular ketene radical cyclization was described.Treatment of α-bromo-β-alkoxycarbonyl- and α-bromo-β-oxoketene dithioacetals with tributyltin hydride and AIBN gave lactones and cyclic ketones bearing bis(methylthio)methylene substituent at α-position in moderate yields.Tandem radical cyclization of ketene radical synthons were also carried out.
