摘要：

Alkylation with n-octyl bromide of several substituted benzoic acids was performed under solvent-free phase transfer catalysis with excellent yields (greater than or equal to 95%) within very short times (2-7 min). Terephthalate octylation was raised from 20% to 92% under microwave activation when compared to conventional heating thanks to inirinsec effects of the radiation.
