Carbyne complexes Catalytic cycle

The proposed catalytic cycle for this unique process includes (i) oxidative addition of a hydrosilane to [Ru—CO] species to form (R3Si)(H)Ru complex 369, (ii) silyl migration to generate siloxycarbyne-Ru species 370, (iii) carbyne reaction with CO to form metal-lacyclopropanone 371, (iv) hydride shift to generate oxyacetylene-Ru complex 372 and... 

The general format of this chapter is the same as that used in previous years. The review is restricted to detectable complexes of Groups 8,9, and 10 which contain a metal-carbon o-bond, including carbenes and carbynes. Species postulated as intermediates (e.g. in catalytic cycles) have been in the main excluded, and coverage of metal-metal bonded complexes has been minimised.
