The authors report here spectroscopic characterization and alkylation and aldol reactions of these Mo(II) enolate complexes as well as the structure of one diastereomer of (Tp')Mo(CO)(P(OPh)/sub 3/)(C(O)CHMEBz), Tp' = hydridotris(3,5-dimethylpyrazolyl)borate). Aldol condensation reactions of transition-metal enolates have not been reported as frequently as alkylation reactions. The authors find that metal enolate reacts with benzaldehyde to yield a deep indigo eta/sup 2/-enone derivative resulting from dehydration of the initial ..beta..-hydroxy eta/sup 2/-acyl product. The formation of (Tp')CO)/sub 2/Mo(eta/sup 2/-C(O)CMe = CHPh) (9) suggests that a range of electrophiles will react with these molybdenum(II) enolate reagents.
