The aldol reactions of tetracarbonyl(phosphine)methyl(methoxy)methylene chromium complexes and pentacarbonylmethyl (dialkylamino)methylene chromium complexes with aldehydes and ketones were examined. The reactions of the phosphine complexes give only

The reactions of 1-(4-hexynyl)methoxymethylenepentacarbonyl complexes 11 of the group 6 metals with alkynes lead to phenol and cyclopentenedione products, both of which are the result of cyclization with one molecule of the external alkyne and the in

The first Michael addition reactions of the anions of aminocarbene complexes to α,β-unsaturated carbonyl compounds are reported. Unlike their corresponding amide enolates, these anions give exclusive 1,4-addition to a number of enones. For chiral c

The reactions of alkyl chromium carbene complexes with alkynes have been found to give cyclopentenones. Mechanisms are proposed to account for the formation of these products that involve metal hydride intermediates. As has been previously reported f

The objective of this study has been to elucidate the mechanism of the rhodium(I)-catalyzed hydroboration process. Evidence that the reaction proceeds through a multistep pathway analogous to that of transition metal catalyzed olefin hydrogenation is

The first examples of intermolecular Diels-Alder reactions of aminocarbene complexes are described. Various members of both the alkylamino and acylamino families of complexes are investigated. The E-isomer of [tran-propenyl(methylamino)methylene]pent
