The synthesis of Unsymmetrical disulphides by cleaving sulphenamides and sulphenic esters with alkyl- and arylthiosilanes and thiols is reported. Alkyl phenyl disulphides and unsymmetrical diaryl disulphides can be prepared conveniently and in 80–90% yield by the interaction of methyl benzenesulphenate and a thiol. Unsymmetrical dialkyl disulphides result from dimethyl or diethyl disulphide and a thiol.
