NaBH/sub 4/ reduction of CO in the cationic iron carbonyl complexes (C/sub 5/Me/sub 5/Fe(CO)/sub 2/L)/sup +/PF/sub 6//sup /minus// (L = CO or phosphine)
C-C bond formations are relevant to the Fischer-Tropsch and related processes such as the hydroformylation of formaldehyde to glycolaldehyde, a precursor of ethylene glycol. The Fischer-Tropsch sequence that consists of the reduction of CO to methyl followed by C-C bond formation and reduction to alkanes is long-known in the Fp series from the work of Atwood. Cutler's studies consisted of the transformation of CpFe/sup +/(CO)/sub 3/ into a variety of C/sub 2/ organic molecules such as CpFeCH/sub 2/OCH/sub 3/ (eq5). CpFe/sup +/(CO)/sub 3/ NaBH/sub 3/CN /yields/ MeOH CpFe(CO)/sub 2/CH/sub 2/OCH/sub 3/. In 1983, the authors reported (Fp*CO)/sup +/PF/sub 6//sup /minus// (1) was reduced by NaBH/sub 4/ to Fp*CH/sub 2/OH (3), Fp*CH/sub 3/ (4), or Fp*H (5) depending on the solvent. They report here full details of the reduction of (Fp*L)/sup +/PF/sub 6//sup /minus// (L = CO (1), P-n-Bu/sub 3/ (9a), PMe/sub 5/ (9b), or PPh/sub 3/ (9c)) by NaBH/sub 4/ and that of 1 by the transition-metal hydrides 5 and H/sub 4/Mo(dppe)/sub 2/ (8). The reactivities of the hydride reduction products especially those of the formyl and hydroxymethyl complexes are discussed. Several aspects of this work have been published as preliminary communications.
