The reactivities of aminoarsines toward diarsines

Academic Article

Abstract

  • The reactions of Me AsNR with Et AsAsEt , and of Et AsNR with Me AsAsMe (R = Me or Et), were investigated over the temperature range 24-75°C by using H and C NMR spectroscopy. The NMR data indicate the initial formation of the unsymmetrical diarsine, Me AsAsEt , and the respective dialkylamino-dialkylarsine, Et AsNR or Me AsNR . The Me AsAsEt then undergoes symmetrization to yield Me AsAsMe and Et AsAsEt . Additional competitive reactions involving AsAs-AsNandAsN-AsN systems also occur in the reaction mixture. In each case, the percentage distribution of products and reactants in the studied systems at equilibrium is independent of temperature within experimental measurement. The reaction rates are dependent upon the nature of R and the alkyl group in the diarsine. In addition, equilibrium constants for several competitive reactions have been determined. © 1987. 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 1 13
