Aryl mercaptans, unlike heterocyclic mercaptans, reacted exceptionally slowly with penicillin sulfoxides.These reactions are affected by the substituent at the C-6 position of the penam, and by the nature of the ester group at the C-3 position.The unsym- azetidinone disulfides obtained from these reactions, unlike those from heterocyclic mercaptans, did not react with halogenating agents such as cupric chloride.

The thermolysis of trichloroethyl 6-phenoxyacetamido penicillanate sulfoxide and ethyl 2-mercaptoacetate in toluene gave the unsym-azetidinone disulfide (β,γ-isomer) in 65percent yield.With added catalytic amounts of N,N-dimethylaniline the α,β-isomer was
