Significant rate enhancement was observed in the liquid-liquid phase-transfer catalytic epoxidations and alkylations under ultrasonic irradiation. Its advantage was also demonstrated in the asymmetric alkylation of tert-butyl glycinate-benzophenone Schiff base using C 2 -symmetric chiral phase-transfer catalyst.
