摘要：

The reactions of a variety of Lewis bases with CH3Mn(CO)5 were examined as a function of time by H1 nmr and infrared spectral methods. Triphenylphosphine, triphenylarsine, and trimethyl phosphite react with CH3Mn(CO)5 to yield a mixture of cis- and trans-CH3COMn(CO)4L complexes. Other phosphorus donor ligands, triphenylstibine, and various amines yield exclusively cis-CH3COMn (CO)4L derivatives. All acetylmanganese complexes, except those with L = amine, were shown to decarbonylate upon heating to yield exclusively cis-CH3Mu(CO)4L. The reaction equilibria are affected by variations in the nucleophilicities and steric requirements of the ligands. A modified methyl-migration mechanism is able to explain the stereochemistry of the products of the decarbonylation reaction. © 1968, American Chemical Society. All rights reserved.
