Abstract: Manganese pentacarbonyl hydride (Mn(CO)5).H is prepared by reacting manganese pentacarbonyl with an alcoholic solution of an alkali metal or alkaline earth metal hydroxide and treating the pentacarbonyl manganate thus formed with a non-oxidising inorganic or organic acid, an acid salt or other acid media whose aqueous solution contains hydrazin ions. Manganese pentacarbonyl is reacted suitably with an alcoholic solution of a hydroxide of Na, K, Li, Rb, or Cs or an alkaline earth metal, e.g. Ca or Ba and methanol, ethanol or propanol, preferably methanol. The resulting solution, containing a pentacarbonyl manganate, may be treated per se with the acid, acid salt or other acid media, or the pentacarbonyl manganate salt may be isolated by evaporation of the solvent and then treated to yield manganese pentacarbonyl hydride. Alternatively, the pentacarbonyl manganate solution may be treated with complexes containing large-volumed cations, e.g. tri-orthophenanthroline nickel (II) salts or stable cation complexes, e.g. (Cr(C6H6)2)+ or (Co(C5H5)2)+, and the resulting complex compound which precipitates being separated and treated with acid to yield the manganese pentacarbonyl. Reference is made to the reaction of the manganese pentacarbonyl hydride with diazo methane to yield a compound of the formula Mn(CO)5.CH3.
