Bal'on, Ya. G.,Smirnov, V. A.
, p. 1635 - 1638 (2007/10/02)
When heated with solutions of potassium or sodium alcoholates in THF of methenol, the readily obtainable N-(aryl-2,2,2-trihalogenoethyl)amides of carboxylic acids gave high yields of N-(1-aryl-2,2-dihalogenovinyl)- or N-(alkoxy-1-aryl-2,2-dihalogenoethyl)
