Two types of novel, sequential and regioselective Friedel-Crafts reactions of gem-dihalocyclopmpanecarbonyl chlorides with benzenes proceeded in a one-pot manner, E-3-aryl-2,2-dihalo-cyclopropanecarbonyl chlorides reacted with substituted benzenes to afford 4-aryl-3-halo- l-naphthols, while 2,2-dichlorocyclopropanecarbonyl chlorides were transformed into 4-aryl-l-naphthols in benzene or p-xylene, Both
宝石-二卤代环丙烷羰基氯化物与苯的两种新颖的,顺序的和区域选择性的弗瑞德-克来福特反应以一锅法进行,E -3-芳基-2,2-二卤代环丙烷羰基氯化物与取代的苯反应得到4-芳基-3-卤代-1-萘,而2,2-二氯环丙烷羰基氯在苯或对二甲苯中转化为4-芳基-1-萘,两种环合均涉及交替和高度区域选择性的环丙烷开环。
