ethynyl(trichloromethyl)carbinol (11a), and 1,1,1-trichloro-3-nonyn-2-ol (11b) have been studied. Whereas the reaction of phenyl(trichloromethyl)carbinol with phosphorus pentachloride leads to a nearly quantitative replacement of the hydroxyl group by chlorine, the reactions of the aliphatic (trichloromethyl)carbinols are more complicated. Thus the reaction of 2 with phosphorus pentachloride gave 18% of the
五氯化磷与乙基(三氯甲基)甲醇(2)、(三氯甲基)-乙烯基甲醇(7)、乙炔基(三氯甲基)甲醇(11a)和 1,1,1-三氯-3-壬炔-2-醇(11b)的反应) 进行了研究。而苯基(三氯甲基)甲醇与五氯化磷的反应导致羟基几乎被氯取代,而脂肪族(三氯甲基)甲醇的反应更为复杂。因此,2与五氯化磷的反应得到18%的正常产物,1,1,1,2-四氯丁烷(3),13%的来自脱卤化氢的1,1,2-三氯-1-丁烯(4),和更高沸点的磷酸酯-酰氯混合物。炔基甲醇(11)通过烯丙基重排得到四氯丁炔(12)和四氯丙二烯(13)。还分离了11a的结晶磷酸酯。给出了 1,1,1-三氯-2-烯烃在气相中催化重排为 1,1,3-三氯-1-烯烃的几个例子。
