Reaction Steps
A solution of 3.5 g. (0.05 mol.) of dimethylketene in ethyl acetate is added dropwise under a nitrogen atmosphere to a cooled (0°) solution of 18.6 g. (0.05 mol.) of 1,3-bis(2-cyano-5-trifluoromethylphenyl)triazene in ether. The reaction mixture is stirred for 12 hours then concentrated at reduced pressure. Crystallization of the residue from ether gives 3-isobutyryl-1,3-bis(2-cyano-5-trifluoromethylphenyl)triazene.
