Chloroform → 4-chloro-N-hydroxybenzene-1-carbonimidoyl chloride

Participants

Reaction Steps

31 g (0.2 mol) of 4-chlorobenzaldoxime was suspended in 200 g of chloroform and chlorine gas was bubbled through the suspension while maintaining the reaction mixture at a temperature of from 5° to 10° C. 3-Chlorobenzaldoxime went into solution while showing a green color upon reaction with chlorine to give a reaction mixture having a deep green color. The reaction mixture turned pale yellowish-brown upon standing; chloroform was then removed from the reaction mixture by distillation under reduced pressure to give 36 g of pale yellowish-brown crystals having a melting point of 75°-80° C. Yield, about 95%.
