Deprotonation of fac-[(κ2P,P-Ph2PCH(R)PPh2)Mn(CO)3Br] (R = H, Me, Ph) produces the corresponding diphosphinomethanide derivatives fac-[(κ3P,C,P-Ph2PC(R)PPh2)Mn(CO)3],

Reaction of [Mn(CO)5X] (X = Cl or Br) with L-L {L-L = dppm (Ph2PCH2PPh2), dppe (Ph2PCH2CH2PPh2), dppp (Ph2PCH2CH2CH2PPh2), C6H4(PPh2)2-o, C6H4(PH2)2-o, dpae (Ph2AsCH2CH2AsPh2), diars [C6H4(AsMe2)2-o], dpsp (Ph2SbCH2CH2CH2SbPh2) or dmsp (Me2SbCH2CH2CH2SbMe2)} or with two molar equivalents of L (= PPh2H, PCy2H or PPhH2) in refluxing CHCl3 yielded the neutral manganese(I) complexes [MnX(CO)3(L-L)] and [MnX(CO)3L2] as yellow or orange solids. Infrared spectroscopic studies confirmed the fac-tricarbonyl arrangement and 1H, 13C-{1H}, 31P-{1H} and 55Mn NMR spectroscopy have been used to probe the solution behaviour. For a given halide 55Mn NMR spectroscopic studies showed some dependence of δ(55Mn) on halide, chelate ring size, substituent and donor atom. X-Ray crystallographic analyses on [MnCl(CO)3{C6H4(PPh2) 2-o}], [MnBr(CO)3(dppe)] and the diprimary phosphine complex [MnCl(CO)3{C6H4(PH2) 2-o}]·CH2Cl2 confirmed a fac-tricarbonyl arrangement, with the ditertiary or diprimary phosphine chelating. The structure of [MnBr(CO)3-(PPhH2)2] also shows a fac-tricarbonyl arrangement with the primary phosphine ligands mutually cis.

The bromo-carbonyls fac-BrMn(CO)3(diphos)(diphos=Ph2P(CH2)nPPh2 for n=1(dpm), 2(dpe), 3(dpp) and 4(dbp)) react with AgClO4 in dichloromethane solution to give the neutral fac-O3ClOMn(CO)3(diphos).The reaction of the latter complexes at room temperature with a variety of ligands L=phosphines (PR3), phosphites P(OR)3), pyridine (Py), acetonitrile (MeCN), tetrahydrothiophene (THT) or acetone (Me2CO) leads to the cationic species fac-ClO4 (or to the ClO4, when L=CO).When L is a phosphorus ligand, the cationic fac-tricarbonyls isomerize upon heating to the mer isomers, which could only be isolated by this method for diphos=dpm, the reaction being accompanied by decomposition in the other cases.UV irradiation of the mer-ClO4 in the presence of a large excess of L gives the corresponding trans-ClO4.
