Access to “Friedel-Crafts-restricted” tert-alkyl aromatics by activation/methylation of tertiary benzylic alcohols
Herein we describe a two-step protocol to prepare m-tert-alkylbenzenes. The appropriate 3° benzylic alcohols are activated with SOCl(2) or concentrated HCl, and then treated with trimethylaluminum, affording the desired products in 68–97% yields (22 examples). This reaction sequence is successful in...
