The stoichiometric reactions of metal complexes which parallel probable steps in the metal catalyzed reduction of CO are being investigated. It is hoped that the study of these model reactions will lead to an understanding of the structural factors influencing these individual reaction steps. The information obtained should be useful in the design and discovery of homogeneous catalysts for the reduction of CO to hydrocarbons. We have studied metal formyl complexes which may be involved in the initiation step in CO reduction and have compared metal formyl compounds with metal acetyl compounds. We have found that the structure and kinetic stability of metal formyl compounds are very similar to metal acetyl compounds. However, metal formyl compounds are thermodynamically much less stable than metal acetyl compounds towards decarbonylation. Hydride donation reactions of metal formyl compounds have been discovered. A neutral metal formyl compound has been discovered and its reactions have been investigated. Preparation of (C/sub 5/H/sub 5/)Re(CO)(NO)(CH/sub 2/OH), the first authentic example of a hydroxymethyl metal compound, was accomplished and studies of its reactions with acid, with base, with CO, and with H/sub 2/ were begun.
