PERFLUOROMETHYL-ELEMENT LIGANDS .20. FORMATION OF HETERONUCLEAR BINUCLEAR COMPLEXES OF THE TYPE-MM'(CO)NXY(M=MN-M'=RE,CO)

The reactions of MnRe(CO)10 with As2(CF3)4 and MnCo(CO)9 with P2(CF3)4, As2(CF3)4, S2(CF3)2, Se2(CF3)2, (CF3)2EI (E = P, As), (CF3)2AsH, (CF3)2AsE′CF3 (E′ = S, Se), (CF3)2PSeCF3, Me2AsI and (CF3)2PPMe2, respectively, have been studied under various conditions. Besides already known mono- and binuclear compounds the heteronuclear complexes MnRe(CO)8[As(CF3)2]2 and MnCo(CO)7[E(CF3)2]2 (E = P, As) are formed. The reactions proceed via cleavage of the MM′ bond and formation of the mononuclear species Mn(CO)5X and M′(CO)nY (M′ = Re, n = 5; M′ = Co, n = 4). © 1979.
