| Abstract: | Reaction of MoX(CO)2(η-C3H5)(MeCN)2] with the arsines Ph2AsCH2CH2AsPh2 (dae) and Ph2AsCH2AsPh2 (dam) yields complexes of stoichiometry MoX(CO)2(η-C3H5)dae] (where X = Cl, Br or I) and MoX(CO)2(η-C3H5)]2dam (where X = Cl or Br). The former are isomorphous with the known Ph2PCH2CH2PPH2 complexes, whereas the latter probably contain halogen and dam bridges. Under forcing conditions the corresponding ditertiary phosphines form the molybdenum(0) derivatives -Mo(CO)2(Ph2P(CH2)nPPh2]2 (where n = 1 or 2). |
