摘要
Aryl(1)(aryl(2))(gem-dichlorocyclopropyl)methanols 1 underwent alternative benzannulation to give ''unsymmetrically'' substituted 1-(aryl(1))-4-chloronaphthalenes 2/A catalyzed by SnCl4 or TiCl4 and to give 1-(aryl(2))-4-chloronaphthalenes 2/B catalyzed by silyl triflates with good to excellent selectivities.
