Participants

Reaction Steps

1.7 g of 4-(2,2'-dicyanovinyl)phenol and 2.7 g of 2,4,5-trichlorobenzenesulfonyl chloride were dissolved in 10 ml of pyridine and reacted at 80° C. for 30 minutes. Crystals were precipitated by cooling to the room temperature and adding water, filtered and recrystallized from toluene to obtain 3.5 g of 4-(2,2'-dicyanovinyl)phenyl 2,4,5-trichlorobenzenesulfonate as white crystals. Melting point=165-166° C.
