The Polarity of the Co-ordinate Link

Abstract

IT has already been shown1 that organic sulphides and tertiary arsines differ markedly in their reaction with chloramine-T. The former give rise to sulphilimines, of formula R2S NSO2C7H7, in which the co-ordinate link is apparently devoid of polar properties: the arsines, however, do not give stable arsinimines, of formula R3As NSO2C7H7, because the co-ordinate link in such compounds apparently possesses sufficient polarity to combine with water, producing thus the corresponding hydroxy-sulphon-amides, R3As(OH).NHSO2C7H7. This behaviour is similar to that of the tertiary arsine-oxides, where the strongly polar link induces ready combination with water to give the dihydroxides, R3As(OH)2.
