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.
