  Reductive Cleavage of Aldehydes to Oxo−Alkylidene and Oxo−Alkylidyne Complexes in Their Reactions with W₂(OCH₂^tBu)₆(py)₂

  摘要：

  Aldehydes react with W-2((OCH2Bu)-Bu-t)(6)(py)(2) to give W-2(mu-CHR)(O)((OCH2Bu)-Bu-t)(6)(py) compounds, where R = alkyl or aryl, which, in the presence of excess pyridine, yield W2(mu-CR)(mu-O)((OCH2Bu)-Bu-t)(5)(py)(2) compounds and neopentanol. A relative order of rates of reductive cleavage of the C=O bond is found to be aryl > alkyl, and for p-X-C6H4CHO, the rates follow the order X = CF3 > H > F > Me > OMe. Four complexes have been structurally characterized by single-crystal X-ray crystallography: W-2(mu-(CHC3H5)-C-c)(O)((OCH2Bu)-Bu-t)(6)(py), 1; W-2(mu-CH(tolyl))(O)((OCH2Bu)-Bu-t)(6)(py), 2; W-2(mu-(CC3H5)-C-c)(mu-O)((OCH2Bu)-Bu-t)(5)(py)(2), 3, and W-2(mu-C(p-MeOC6H4))((OCH2Bu)-Bu-t)(5)(py)(2), 4. Factors influencing the reductive cleavage of the C=O bond are discussed in light of earlier studies of related reactions, and most notably comparisons are made with the development of a molecular alternative to the McMurry reagent.
