used to trap sulfenic acids from penicillin sulfoxides. Kamiya et al1 first reported the preparation of unsymmetrical azetidinone disulfides Lfrom penicillin sulfoxides and utilized this disulfide L for the derivatization of the B-methyl group in penicillins. Since then, "Kamiya's disulfide" has fou
## Abstract A general procedure for the synthesis of Ξ±β(phenylseleno)sulfinyl and βsulfonyl alkenes has been described. 1β(Phenylseleno)ethenyl sulfoxides were prepared by the __syn__βaddition of in situβgenerated sulfenic acids on to the triple bond of suitably substituted (phenylseleno)acetylenes
