The synthesis of novel palladium(ii) carbene complexes, azolium salts and their catalytic properties

Abstract

Novel three 1,3-bis[2-(N,N'-diisopropylamino)ethyl]imidazolinium, 1,3-bis[2-(N,N'-diisopropylamino)ethyl]benzimidazolium and 1-(2-diisopropylaminoethyl)-3-(2-methoxyethyl)benzimidazolium chloride salts (1, 3a-b) and two palladium complex (2, 4) have been prepared and characterized by C, H, N analysis, H-1 NMR and C-13 NMR and they have been investigated their catalytic activity in the Heck and Suzuki coupling reactions.
