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

Résumé

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