An electrochem. method for the hydrogenation of ketones RC(O)R1 [R = Me, Et; R1 = CH3, CH2CH3, (CH2)2CH3, (CH2)2CH=C(CH3)2, (CH2)2CH=CH2] and aldehydes R2CHO [R2 = (CH2)3CH3, (CH2)4CH3, (CH2)2CH=CH2] by in situ formation of a Mn-H species has been described. The protons and elec. current as surrogate for H2 and a base-metal complex to form selectively the alcs. RCH(OH)R1 and R2CH2OH have been described. The method is chemoselective for the hydrogenation of C=O bonds over C=C bonds. Mechanistic studies revealed initial 3 e- reduction of the catalyst forming the steady state species [Mn2(H-1L)(CO)6]-. Subsequently, the protonation, reduction and internal proton shift forming the hydride species has been described. Finally, the transfer of the hydride and a proton to the ketone yields the alc. and the steady state species is regenerated via reduction The interplay of two manganese centers and the internal proton relay represent the key features for ketone and aldehyde reduction as the resp. mononuclear complex and the complex without the proton relay are barely active.
