Dimethylarsine and dimethylhaloor pseudohaloarsines, X Cl, Br, I or CN, reversibly form tetramethyldiarsine and HX in benzene. As followed by pmr spectroscopy, several pmr-rapid processes are observed which involve the exchange of parts among equilibrium components. Where available, equilibrium and thermodynamic parameters have been obtained. The activational parameters for the exchange processes suggest that exchange occurs through an associative intermediate. When X Br or I, significant quantities of H2 are also found.
