Silaallyl− and silapentadienyl−iridium−phosphinecomplexes have been synthesized via the reaction of “(Me)Ir(PMe3)3” with vinyl- and butadienyldimethylsilanes. Upon heating, these complexes lose methane and undergo a variety of reactions, including C−H bond activation to produce a five-membered iridasilacycle, CC bond coordination to generate an η1,η2-silapentadienyl ligand, and decomposition.

e3)3, 7E or 7Z. Heating these compounds in toluene or benzene (under pressure) leads to methane loss, followed by C−H bond activation. In the case of 7E, a silapentadienyl methyl group is activated, producing an iridasilacyclopentene product, 8. In the case of 7Z, a C−H bond on the end of the silapentadienyl chain is activated, producing the first example of an iridasilacyclohexadiene, 9. X-ray crystal
