for the cyclization of vicinal X-H substituted amines to provide various five-membered heterocycles. However, arylamines are required to be used and difluoromethylation of the NH bond or a newly generated S-H bond cannot be suppressed. Herein we describe the use of thiocarbonyl fluoride generated in situ as a thiocarbonyl source for the cyclization of vicinal X-H substituted alkyl amines (X = N, O
