Catalytic addition reactions of amines, thiols, and diphenyl‐phosphine oxides to heterocumulenes using a bridging Sulfonylimido titanium(IV) complex

We present here an efficient method for hydroelementation reactions such as hydroamination, hydrothiolation, and hydrophosphorylation of the heterocumulenes carbodiimides, aryl isocyanates, isothiocyanates with anilines or thiophenols using a p-tolylsulfonylimide-supported dinuclear titanium complex. All were achieved in excellent yield under mild conditions within short reaction time. The products isolated fully characterized by spectroscopic techniques. also propose mechanism involving proton abstraction (of E−H thiophenols) first step. In mechanism, amido groups binuclear TiIV complex act leaving group whereas sulfonylimide linkage remains unaffected.
