Two types of novel, sequential and regioselectiveFriedel-Craftsreactions 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
