Ionic cleavage of Ti–Co and Zr–Co bonds: the role of the nucleophilicity of the late transition metal in the reactive behaviour of early–late heterobimetallics
Abstract
The ionic cleavage of Ti–Co and Zr–Co bonds occurs upon reaction with ButNC and the products [MeSi{SiMe2N(p-Tol)}3Ti(CNBut)2][Co(CO)4] 3 and[MeSi{SiMe2N(p-Tol)}3Zr(CNBut)3][Co(CO)4] 4 were characterized by single crystal X-ray diffraction; the importance of the nucleophilicity of the late transition metal fragment in reactions of the unsupported early–late heterobimetallics is demonstrated.
