Urethanes of the type SF5NHC(O)OR react with PCl5 to give primarily SF5NCO.In only one case, where R = C6H5, was any evidence for an imine product observed.The corresponding reactions of SF5NHC(O)SR compounds give both SF5NCO and the imine product.The new compounds SF5N=C(Cl)SCH3 and SF5N=C(Cl)SC6H5 were identified by IR, NMR, and mass spectrometry.
