Cationic alkylidyne trirhodium cluster complexes. Crystal structure [(.eta.5-C5H5)3Rh3(.mu.-CO)2(.mu.3-CH)]PF6[tris(.eta.5-cyclopentadienyl)-bis(.mu.2-carbonyl)-.mu.3-methylidyne-trirhodium] hexafluorophosphate

Reaction of a (π-Vinylcarbene)iron Complex with Tricarbonyl(η4-1,5-cyclooctadiene)ruthenium. Preparation, Structure, and Reactivity of Novel (μ-Vinylcarbene)(Fe−Ru) Complexes

“…For the past two decades, much attention has been focused on the chemistry of mononuclear 1 − and binuclear transition-metal vinylcarbene complexes 2 , (η 4 -metallabutadiene)metal complexes 2 ‘, or η 3 :η 1 -allylidene complexes 2 ‘‘ (Chart ). − Especially, heterobinuclear vinylcarbene complexes − are of interest; however, methods of preparation of these complexes are not completely established. As for the preparation of (μ-vinylcarbene)(M 1 −M 2 ) complexes, the following two representative methods are reported: (1) reaction of (μ-methylene)(M 1 −M 2 ) 3 with alkynes (eq 1); (2) reaction of (η 1 -vinylcarbene)M 1 or 1-metallabutadiene 4 with M 2 (eq 2) .…”
