New polyethylene glycol ammonium and phosphonium salts (PEG-quat) phasetransfer catalysts were synthesized and their catalytic activity was studied in a dehydrohalogenation liquid-liquid phase-transfer system. The catalytic activity of the PEG-quat catalyst depended on the nature of the quaternary s
