Chloroform → alpha-Chloro-3-nitrobenzaldoxime

Participants

Reaction Steps

32.9 g (0.2 mol) of 3-nitrobenzaldoxime was suspended in 150 g of chloroform and chlorine gas was bubbled into the suspension while maintaining the reaction mixture at a temperature of from 5° to 10° C. 3-Nitrobenzaldoxime went into solution showing a green color upon reaction with chlorine to give a reaction mixture having a deep green color. The reaction mixture turned a pale yellowish-brown upon standing; chloroform was then removed from the reaction mixture under reduced pressure to give 37.6 g of pale yellow crystals having a melting point of 98°-101° C. Yield, 94%.
