Reactions of Alkylphosphorus, Arsenic, and Antimony Hydrides and Halides with Dibenzylmercury. An Improved Procedure for Cyclopolyarsines.

Abstract

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, (CH3P)5, (CH3As)5 and C2H5As)5 respectively. From CH3SbH2, both the solid, polymeric product, (CH3Sb)x, is obtained. With (CH3)2AsH, both the condensation product, (CH3)2AsAs(CH3)2, and the substitution product, (CH3)2AsCH2C6H2, 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) CH3As(CH2C6H5)2, and with (CH3)2AsI, (CH3)2AsCH2C6H5. In all cases the conversion of starting materials to the indicated products is very high. (Author)
