Enamino-thiones of the general type ArC(S)CH:CHNR2,3(Ar=phenyl p-methoxyphenyl and p-bromophenyl NR2= pyrrolidinyl piperidinol were prepared by reacting the corresponding enaminones 2 with 2,4-bis-(4-methoxyphenyl) 1,3,2,4-dithiadiphosphetane 2,4-disultide 1. The compounds 3 were reacted with methyl iodide and ethyl iodide to give exclusively S-alkylated iminium iodides 4 and 5, in quantitative overall
