Abstract

The reduction chemistry of the newly emerging 2-phosphaethynolate (OCP)(-) is not well explored, and many unanswered questions remain about this ligand in this context. We report that reduction of [Th(Tren(TIPS))(OCP)] (2, Tren(TIPS)=[N(CH2CH2NSiPr3i)](3-)), with RbC8 via [2+2+1] cycloaddition, produces an unprecedented hexathorium complex [{Th(Tren(TIPS))}(6)(mu-OC2P3)(2)(mu-OC2P3H)(2)Rb-4] (5) ...
