Abstract
A series of electron-rich arenes were reacted with 1-alkyl or 1-aryl 1′-allyl benzylic alcohols to give the corresponding 1,1′-diarylalkanes, in the presence of Lewis and Brønsted acids as catalysts. In the presence of HBF4, 1,1′-diarylalkanes containing an allylic chain were shown to form tetrahydronaphthalenes through a rearrangement involving spirocyclic intermediates. The mechanism of the cyclization is discussed.

Abstract
Iron salt-catalyzed Friedel-Crafts alkylation of chiral α-aryl alcohols with a trimethylsilyl group was found to proceed with retention of the configuration of the hydroxyl group as a leaving group. The memory of chirality of this system stems from the β-silyl effect of the trimethylsilyl group on the carbocation intermediate.
