Reaction Conditions

Reaction Steps

A 5.0 g (0.0281 mol) sample of 3-chloropropylsulfonyl chloride was added slowly at about 0° C. (ice bath) to a suspension of 6.7 g (0.0281 mol) of the sodium salt of alpha-cyano-2,6-dichlorobenzaldoxime in 60 ml benzene. The reaction was exothermic. The reaction mixture was stirred at 25° C. for 2 hours during which time a solid product formed. The reaction mixture was then diluted with 200 ml dichloromethane, washed with water, dried over magnesium sulfate and silica gel, and evaporated under reduced pressure to give a yellow oil. The oil was crystallized from ether/hexane to give the product as white crystals, m.p. 86°-88° C. This product is tabulated in Table I as compound No. 12.
