The reactions proceed by use of a sulfonic acid such as TosOH, TfOH etc. in a non-polar solvent. Addition of a catalytic amount of m-MeC6H4SH improves the yield of product (VI). The mechanism o
## Abstract The reactions of 3‐phenyl‐1‐azabicyclo[1.1.0]butane with __α__‐chlorosulfenyl chlorides and sulfinyl chlorides lead to the corresponding sulfenamides and sulfinamides, respectively, which possess an azetidine ring. It is proposed that a two‐step mechanism occurs involving an intermediat
