000169442 5203_ $$aComplex [Os(═CHPh)(CH3CN)4(IPr)](OTf)2 (1) (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolylidene; OTf = CF3SO3) exchanges the alkylidene group with propylene to give styrene and [Os(═CHCH3)(CH3CN)4(IPr)](OTf)2 (2). The reaction of 1 with ethylene leads to [Os(η2-CH2═CH2)(CH3CN)4(IPr)](OTf)2 (3) via the propylene intermediate [Os(η2-CH2═CHCH3)(CH3CN)4(IPr)](OTf)2 (4). Acetonitrile displaces the olefin ligand of both 3 and 4 to generate the pentakis(solvento) derivative [Os(CH3CN)5(IPr)](OTf)2 (5). In 2-propanol and methanol, complex 5 reacts with 1,1-diphenyl-2-propyn-1-ol and 2-methyl-3-butyn-2-ol to yield the corresponding alkoxyalkenylcarbene compounds [Os{═C(OR)CH═CR′2}(CH3CN)4(IPr)](OTf)2 (R = CH(CH3)2; R′ = Ph (6), CH3 (7); R = CH3; R′ = Ph (8), CH3 (9)). The X-ray structures of 4, 5, and 6 are also reported.
