Rr. Deshmukh et al., Ultrasound promoted C-C bond formation: Heck reaction at ambient conditions in room temperature ionic liquids, CHEM COMMUN, (17), 2001, pp. 1544-1545
Heck reaction proceeds at ambient temperature (30 degreesC) with considerab
ly enhanced reaction rate (1.5-3 h) through the formation of Pd-biscarbene
complexes and stabilized clusters of zero-valent Pd nanoparticles in ionic
liquids under ultrasonic irradiation.
