Abstract
We have developed an efficient method for carbon–carbon cross coupling reactions using a palladium-catalyst supported on porous silica gel confined ionic liquid, 1-decyl-3-methyl imidazolium fluoroborate ([dmim]BF4) in water at 80 °C. A variety of substituted aryl bromides underwent Suzuki and Heck coupling with various boronic acids and acrylates respectively to produce a series of functionalized biaryls and cinnamates in high yields. The catalyst is stable, recyclable and it offers very high turnover numbers.
