1,1-Bis(R-phenyl)-2,2,2-trichloroethanes are dehydrochlorinated in high yields, e.g., into 1,1-bis(chlorophenyl)-2,2-dichloroethylenes, by reacting same with an aqueous solution of an alkali metal hydroxide, in liquid state in the presence of a phase transfer agent, e.g., a quaternary ammonium compound, but in the absence of any reaction solvent.
1,1-双(R-苯基)-2,2,2-三氯乙烷通过与碱金属氢氧化物的水溶液反应,在液态状态下,在存在相转移剂(如季铵化合物)的情况下,但不含任何反应溶剂,可以高产率地脱氯化,例如,生成1,1-双(氯苯基)-2,2-二氯乙烯。
