Inverse Phase Transfer Catalyst

An environmentally benign, scalable and highly selective C-arylalkylation of active methylene compounds is developed using CTAB as the inverse phase transfer catalyst. The methodology is also applicable to the regioselective synthesis of N-aralkyl/alkyl 2-pyridones.
