Electrophillc benzylations of 2,6-dimethylphenol and its ethers give surprisingly hia yields of products of attack at m&a-positions of the aromatic rings.1 Examination of possible mechanisms for meta-benzylation showed that only direct attack at the r&a-positions was consistent with sll the evidence
Hydmw and alkoxy groups on aromatic rings are powerful ortho-w directing substituents in -electrophlllc substitution reactions. We have confirmed, for instance, previous reports1 that Friedel-Crafts benzylatlcm of phenol, anisole, snd orthc-cresol gives solely products of substltution at positions o
