| Summary: | Bibliography: p. 125-129. === Transition metal methoxymethyl and chloromethyl complexes may be versatile starting materials for the synthesis of several types of new complexes, including hydroxymethyl and carbene complexes, respectively [LₙMCH₂OH] and [LₙMCH₂]⁺ (M=transition metal, L=ligands). Hydroxymethyl and carbene transition metal complexes are models of catalytic intermediates in the Fischer-Tropsch reaction. We have synthesized the new chloromethyl complexes [Ru(Cp)(CO)₂CH₂CI], [Re(CO)₅CH₂CI], and cis-[Mn(CO)₄(PPh₃)CH₂CI], and the new methoxymethyl The existence of rotational isomerism in the complexes [Ru(Cp)(CO)₂CH₂ocH₃] and the previously reported [Fe(Cp)(CO)₂CH₂OCH₃],⁴⁸ is proposed on the basis of infrared data. Mass spectra of several methoxymethyl and chloromethyl transition metal complexes have been recorded.
