Electroreduction of carbonylmanganese(I) cations. Mechanism of ligand substitution and hydride formation via manganese(0) intermediates

Hydridomanganese(I) complexes (OC)3MnL2H are the principal products from a series of acetonitrile derivatives of carbonylmanganese cations, i.e., (OC)3Mn(NCMe)nL3-n+ (I), when the reductions are carried out electrochemically in the presence of added phosphines L. Cyclic voltammetric studies show that the conversion to the hydride can be formulated in three discrete stages. First, the carbonylmanganese cation such as (OC)3Mn(NCMe)3+ with n = 3 undergoes an electrocatalytic ligand substitution with added L to form the bis(phosphine) complex (OC)3Mn(NCMe)L2+ via labile 19-electron Mn(0) intermediates as in Scheme V. Second, the substitution product (OC)3Mn(NCMe)L2+ is reduced to the Mn(0) radical (OC)3Mn(NCMe)L2?; which is common to all cationic precursors irrespective of the degree of prior phosphine coordination in the precursor I (i.e., n = 1, 2). Third, the hydridomanganese product is derived by hydrogen atom transfer to the carbonyl ligand of the 19-electron intermediate (OC)3Mn(NCMe)L2? to form the formyl complex (OC)2Mn(NCMe)L2CHO, followed by the electrocatalytic extrusion of the coordinated ligand (MeCN) as in Scheme III. The third stage is established in the reductive conversion of the cationic (OC)4Mn(PPh3)2+ to the hydride (OC)3Mn(PPh3)2H by the observation of the intermediate (OC)3Mn(PPh3)2CHO during cyclic voltammetry. A competition to form the carbonylmanganate (OC)3MnL2- as a byproduct of reduction is also delineated.

Electrosynthesis of Hydridometal Carbonyls. Rapid Ligand Substitution in Transient Mn0 Intermediates from the Reduction of Carbonylmanganese(I) Cations

Unusually enhanced rates of multiple ligand substitutions are observed during the convenient synthesis of hydridomanganese complexes by the cathodic reduction of carbonylmanganese cations.
