Abstract

MICHAELIS and KOHLER showed that when the phosphonium salts Ph3P* CH2* COR+ X- (R= Me or Ph), prepared by the action of triphenylphosphine on the corresponding a- halogeno-ketones, were treated with aqueous alkali, stable halogen-free compounds were obtained. They were termed phosphobetaines and assigned the structure (11). Wittig and Sehollkopf obtained the phosphonium salt (I; R= Ph) by reaction of ...
