Heck reaction of olefin

The Heck reaction of olefins with aryl halides proceeds successfully in the presence of palladium catalyst supported on TMG (1) modified molecular sieves without solvent. The TMG-Pd was found to be much more active and stable than the palladium catalyst without modification with TMG (1) [87]. An ionic liquid, tetramethylguanidinium lactate, was used as the TMG source.
