Abstract

The reactions of RLi (R = t-Bu, m-F3CC6H4) with bis(dimethylamino)chloroarsine in diethyl ether at room temperature result in the formation of t-butyl-bis(dimethylamino)arsine (1) and m-trifluoromethylphenyl-bis(dimethylamino)arsine (2). Compounds 1 and 2 were hydrolysed in water solution in the presence of sodium carbonate to give the oxides (t-BuAsO)(n) (3) and (m-F3CC6H4AsO)(n) (4) respectively. The X-ray crystal structure of 4 shows the molecule to be cyclotetrameric with pyramidal arsenic. Copyright (C) 2004 John Wiley Sons, Ltd.
