Abstract
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. © 2022 Wiley-VCH GmbH.
