Organocobalt Cluster Complexes. XXIII. Clemmenszn and Borane Reductions of Acyl-and Vinylic Methylidynetri-Cobalt Nonacarbonyl Complexes

摘要

The Clemmensen reduction is an effective means of converting acyl- and vinylic methylidynetricobalt nona-carbonyl complexes to the corresponding saturated alkylidynetricobalt nonacarbonyl when it is carried out in nonaqueous medium. Diborane in tetrahydrofuran reacts with acyl-substituted cobalt clusters to give a mixture of the corresponding alcohol and alkyl complexes in which the latter predominates.
