Chloroacetyl chloride → HCID 21516372, compound

Participants

Reaction Steps

A solution of 10.0 g. (0.026 mol.) of 1,3-bis(2-cyano-5-trifluoromethylphenyl)triazene and 1.8 g. (0.037 mol.) of 50% sodium hydride in ether is added to a solution of 3.2 g. (0.028 mol.) of α-chloroacetyl chloride in 25 ml. of ether. The reaction mixture is stirred at 25° for one hour then filtered. The filtrate is concentrated under reduced pressure to give 3-(2-chloroacetyl)-1,3-bis(2-cyano-5-trifluoromethylphenyl)triazene as an oil which crystallizes upon trituration with isopropyl ether, m.p. 98°-100°.
