Aryll(aryl2)(gem-dichlorocyclopropyl)methanols 1 underwent alternative benzannulation to give "unsymmetrically" substituted l-(aryll)-4-chloronaphthalenes 21A catalyzed by SnCI4 or TiCI4 and to give 1-(aryl2)-4-chloronaphthalenes 2/B catalyzed by silyl triflates with good to excellent selectivities.
