Abstract
An efficient and ligandless catalytic system was developed for the Suzuki- Miyaura coupling reactions of potassium aryltrifluoroborates in pure water. Using TEAB as additives, Pd(OAc)2 was found to be very efficient for the Suzuki-Miyaura coupling of potassium aryltrifluoroborates with various aryl and heteroaryl bromides in pure water with Na2CO3 as a base, affording the desired products in moderate to excellent yields. Keywords: Suzuki-Miyaura coupling reaction, potassium aryltrifluoroborate, aryl bromide, heteroaryl bromide, water, palladium acetate.
