The hydroxymethyl complexes (η5 -C5H5)M-(CO)2(CH2OH) (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, Crl3C(0)CI/C5H5N, and (CH3)3SICI/ C5H5N to form methoxymethyl, (acyloxy)methyl, and (trimethylsiloxy)methyl complexes. Only the (trimethylsil-oxy)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 psi at 80 °C.
