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 Bu^tNC and the products [MeSi{SiMe₂N(p-Tol)}₃Ti(CNBu^t)₂][Co(CO)₄] 3 and[MeSi{SiMe₂N(p-Tol)}₃Zr(CNBu^t)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.
