The Ekbom method as improved by the writer was expected to be useful as a process for the preparation of alkylated, arylated, or aralkylated heterocyclic disulfides, not possessing other functional groups in general and the process was applied to alkane-, arene-, and aralkaneylsulfonyl chlorides. Corresponding disulfides were obtained from alkane- and arenesulfonyl chlorides but phenylmethane-sulfonyl chloride, as one of the aralkane series, only afforded dibenzyl sulfide and not the disulfide. Of the heterocyclic sulfonyl chlorides submitted to the reaction, 2-thiophenesulfonyl chloride failed to afford any product under these conditions and the starting material was recovered. Even in this case, the disulfide was obtained by the addition of a calculated amount of iodine and carrying out the reaction at a low temperature.
