Phenylarsenic(III) complexes of 2-(2-hydroxyphenyl)benzothiazolines

Equimolar reactions of PhAs(OMe)2 (prepared in situ) and 2-(2-hydroxyphenyl)benzothiazolines LH2 give the addition products PhAs(OMe)2LH2, while equimolar reactions of PhAsCl2 with Na2L yield substitution products PhAsL. All these derivatives have been characterized by elemental analyses and their plausible structures have been established on the basis of physico-chemical, IR, and NMR (1H and 13C) spectral studies. © 2003 Wiley Periodicals, Inc. 15:92–96, 2004; Published online in Wiley InterScience (www.interscience.wiley.com).
