Abstract
Triphenyl-phosphine and -arsine react with manganese(II) halides to produce Mn(OEPh3)2X2(E = P, As; X = Cl, Br, I) complexes; this implies than an earlier report of Mn(EPh3)2X2 complexes is mistaken. Similarly the bidentate ligands bisdiphenylphosphinomethane, cis-1,2-bisdiphenylphosphinoethylene, 1,2-bisdiphenylphosphinoethane, and 1,2-bisdiphenylarsinoethane react with MnX2 to form Mn(ligand dioxide)X2 complexes. Manganous chloride and bromide react with diphenylphosphine to form bis(diphenylphosphinite)manganese(II), a novel reaction involving both ligand deprotonation and oxidation. A possible mechanism of the oxidation of these ligands is discussed.Keywords
