The hydroxymethyl complexes (η5-C5H5)M-(CO)2(CH 2OH) (M = Ru, Fe) were isolated from the reduction of the tricarbonyl cations (η5-C5H5)M(CO)3 + with 4 equiv of NaBH3CN. They decompose catalytically to (η5-C5H5)Ru(CO)2H or [(η5-C5H5)Fe(CO)2]2 and formaldehyde when treated with phosphorus ligands. They react with CH3OH, CH3C(O)Cl/C5H5N, and (CH3)3SiCl/ C5H5N to form methoxymethyl, (acyloxy)methyl, and (trimethylsiloxy)methyl complexes. Only the (trimethylsiloxy)methyl complexes can be hydrolyzed to regenerate the hydroxymethyl precursors. No CO insertion reactions were observed for any of these products at pressures up to 4000 psl at 80°C.
