react with secondary amines such as morpholine or dicyclohexyl amine. All these displacement reactions proceed with almost complete stereochemical integrity at the phosphorus atom. These abservations support a synchronous mechanism of bond breaking and bond formation during nucleophilicdisplacement at the dicoordinate sulfur atom. The same can be said about the reaction of sulfenamides 9a,b,c with hydrogen
