Abstract The reaction between NaAs (CH 3) 2 and o-Cl 2 (C 6 H 4) has been studied and the following products identified:(CH 3) 2 AsH, o-[(CH 3) 2 As] 2 [C 6 H 4],(CH 3) 3 As,(CH 3) 2 As (C 6 H 5), 5, 10-dimethyl-5, 10-dihydroarsanthren and methylbis [o-(dimethylarsino) phenyl] arsine. The reaction between NaAs (CH 3) 2 and cis-1, 2-dichloroethylene gives a mixture of cis-and trans-1, 2-bis (dimethylarsino) ethylene, while 1, 2-dibromoethylene ...
