Abstract

The novel bimetallic µ-diboranyl–oxycarbyne bridged platinum–tungsten complex [W{η¹,µ-CO-B(NMe₂)-B(NMe₂)-(η⁵-C₅H₄)}(CO)₂{Pt(PPh₃)₂}] (W–Pt) (3) has been synthesised by a two-step reaction, starting from the dilithiated half-sandwich compound Li[W(η⁵-C₅H₄Li)(CO)₃] (1) via the ansa-diboranyl–oxycarbyne tungsten complex [W{η¹-CO-B(NMe₂)B(NMe₂)(η⁵-C₅H₄)}(OC)₂] (2) by use of stoichiometric amounts of B₂(NMe₂)₂Br₂ and [Pt(η²-C₂H₄)(PPh₃)₂], respectively.
