摘要

One-electron oxidation of the carbyne complex (eta(5)-C5H5)(CO){P(OPh)(3)}Mo=CCH2CH2CH2CH3 (1a) in the presence of phenylacetylene results in H-abstraction and addition of the alkyne to the resulting metal carbene. The final product of the addition is the eta(1)eta(2)-allyl complex (eta(5)-C5H5)(CO){P(OPh)(3)}Mo[eta(1):eta(2)-CH{P(OPh)(3)}C(Ph)=CH(Ch(2)CH (2)CH(2)CH(3))] (2a), the structure of which was confirmed by X-ray crystallography.
