Treatment of pentacarbonyliron with pentafluorophenylacetylene has given the stable complex tricarbonyl-2,5-bis(pentafluorophenyl)cyclopentadienoneiron. There is no evidence of the formation of other structural isomers. The complex is also formed from pentafluorophenylaoetylene and nonacarbonyldiiron or dodecacarbonyltriiron. Two alkyne-cobalt complexes have been isolated from the interaction of octacarbonyldicobalt and pentafluorophenylacetylene. One of these is a bridging alkyne complex of molecular stoicheiometry Co2(CO)6(C6F6CCH); the second is a complex of formula Co3(CO)9(CCH2C6F5). The infrared and nuclear magnetic resonance spectra of the complexes are given, and the probable structures of the compounds are deduced from these spectroscopic properties.

Formation Of Complexes

Two new organocobalt complexes, Co2(CO)4(CF3C2CF3)3 and Co2(CO)4(CF3C3H)2- CF3C2CF3, have been isolated from the appropriate reactions of hexafluorobut-2-yne with octacarbonyldicobalt and of 3,3,3- trifluoropropyne with μ-hexafluorobut-2-yne-hexacarbonyldicobalt. The probable structures of these compounds are discussed in light of their infrared and nuclear magnetic resonance spectra. ��� The direct formation of complexes of the type Co3(CO)9CCH2R has been established in the reactions of several terminal alkynes, RC2H (R = H, CF3, C6H5), with octacarbonyldicobalt. The spectroscopic properties of the products so obtained are given.
