The authors have recently shown that the Ru(II)-Sn(II) bimetallic complex can catalyze the unprecedented one-step formation of acetic acid (or methyl acetate) with methanol used as the sole source. It was suggested that the reaction consists of sequential processes of methanol {r_arrow} formaldehyde (methyl){r_arrow}methyl formate {r_arrow} acetic acid (methyl acetate). While the Ru(II) complexes capable of catalyzing the dehydrogenation of methanol into methyl formate are known, this catalyst system is unique because of its extra ability to isomerize methyl formate to acetic acid without a CO atmosphere (usually high pressure) or an iodide promoter (often corrosive to reaction apparatus). In this communication, the authors examine the cyclopentadienyl bis(triphenylphosphine) ruthenium(II) auxilliary in view of its well defined geometry and configurational stability, and demonstrate that combination with the SnF{sub 3} ligand gives quite high catalytic ability compared to the conventional SnCl{sub 3} ligand. 12 refs., 1 fig.
