Abstract

Abstract Während Alkylsulfone Nitrile unter Bildung von β‐Imino‐alkylsulfonen [wie z.B. (IV)] addieren, reagiert Dimethylsulfoxid mit den Nitrilen (Ia) und (Ib) zu den (a‐ Methylmercapto‐β‐aryl‐β‐imino‐ethyl)‐methyl‐sulfoxiden (IIa) bzw. (IIb), die mit CS2 K11 die Thiazolthione (IIIa) bzw. (IIIb) geben; analog wurden (IIIc) ‐ .(IIIe) erhalten.
