Dibenzylmercury is a convenient and general reagent for the formation of homoatomic catenates from primary alkyl phosphines, arsines and stibines. From CH3PH2,CH3AsH2 and C2H5AsH2, the products are Hg and the cyclopentamers, CH3P5, CH3As5 and C2H5As5 respectively. From CH3SbH2, both the solid, polymeric product, CH3Sbx, is obtained. With CH32AsH, both the condensation product, CH32AsAsCH32, and the substitution product, CH32AsCH2C6H2, are obtained. With dibenzylmercury, CH3PC1, CH3AsCl2, and CH3SbCl2 give only the mono-substitution product CH3ECH2C6H5Cl E P, As or Sb and HgCl2. With CH3AsI2, disubstitution occurs giving in addition to HgI2 CH3AsCH2C6H52, and with CH32AsI, CH32AsCH2C6H5. In all cases the conversion of starting materials to the indicated products is very high. Author
