Reaction chemistry of tricarbonyl-η5-pentadienylmanganese: Straightforward synthesis of stable manganese carbonyl terminal thiolates and a dinuclear bis(ethylenediaminyl) complex

Tricarbonyl-η5-pentadienylmanganese reacts with mercaptans RSH, R = Ph, C6F5, m-NH2C6H4, p-NH2C6H4, and HSCH2CH2 in the presence of ECH2CH2E, E = –PPh2 or –NH2 to give novel stable terminal thiolate mononuclear complexes fac-Mn(CO)3(SR)(Ph2PCH2CH2PPh2-κ2-P,P′) for R = Ph, C6F5, m-NH2C6H4, p-NH2C6H4, and HSCH2CH2 and fac-Mn(CO)3(SR)(H2NCH2CH2NH2-κ2-N,N′) for R = Ph and C6F5. Upon reaction of tricarbonyl-η5-pentadienylmanganese with ethylenediamine a dinuclear complex [fac-Mn(CO)3(μ-H2NCH2CH2NH-κ2-N,N′)]2 was formed wherein the diaminyl ligand functions in the capacity of chelating and bridging ligand.
