| Abstract: | Cleavage of the E-P bond in compounds of the type (CF3)2EPh2(E = P, As) is achieved by polar HBr, (CF3)2EI, (CH3)3SnH, (CF3)2AsH] and non-polar Br2, Mn2(CO)10] substances. Exchange reactions are possible with (CF34)E2 and P2F4 leading to the unsymmetrical compounds (CF3)2PPF2, (CF3)2AsPF2, (CF3)2PAs(CF3)2, F2PPH2, (CF3)2AsPH2. The reaction of (CF3)2PPH2 with Mn2(CO)10 gives the new binuclear complex Mn2(CO)8PH2P(CF3)2 and Mn2(CO)8P(CF3)2]2. The hitherto unknown compound (CF3)2AsPF2 is obtained by the reaction of (CF3)2AsPH2 with P2F4. Adducts of (CF3)2PPH2 with B2H6 and (CH3)3N, respectively, are discussed. Investigation of the reaction route and characterization of most of the reaction product is based on 1H and 19F NMR spectral data. |
