Abstract

Sulfenylation of active methylene compounds with disulfides and CCl~4~/base, proceeding in two steps, gives rise to more than 50% of the introduced sulfur component due to the reoxidation of the thiolate into the starting disulfide. Depending on the reaction conditions, arylacetonitriles and diaryl disulfides react to form mono‐ or bis‐sulfenylated products. By use of this method, a number of previously unknown Ξ±, α‐bis‐sulfenylated nitriles were prepared.

## Abstract A novel method for the preparation of thioesters starting from Iso‐__Fujisawa__ disulfides is reported. The presence of an acylamino group __cis__ to the disulfide function on the β‐lactam nucleus seems to be an essential requirement for this reaction. In the absence of such a __cis__‐a
