Abstract: | Palladium polyether diphosphinite complex anchored on polyethylene glycol is reported as an efficient catalyst for Heck coupling reactions. The catalyst is soluble in the solvent with reactants and products during reaction and can be separated from reaction media in biphasic form by the addition of anti-solvent like n-hexane and further recycled. The developed methodology offers mild reaction condition, short reaction time with an excellent recyclability of the catalyst. Aryl iodides as well as aryl bromides are well tolerated giving excellent yields. |
