Réactivité d'hydrures de tantalocène : insertion du soufre dans la liaison tantale-hydrogène

Abstract

In the course of our research concerning the reactivity of tantalocene hydrides towards elemental sulfur, the synthesis of monosulphurated complexes by a sulfur insertion reaction into the Ta-H bond is reported. Some information on the mechanistic pathway for the formation of the disulfide complexes and the synthesis of Cp′₂Ta(CO)(SH) is given.
