The catalytic activity of palladium(ii)-1,3-bis[(4- nitrophenyl)methyl]-1-benzimidazolium bromide complexes in heck reaction / Nur Atikah Syahidah Rosli

N-heterocyclic carbene ligand is used to synthesize palladium(II) complex which involves in Heck reaction as catalyst. In this study, the 1,3-bis[(4- nitrophenyl)methyl]-l-benzimidazolium bromide which is one of N-heterocyclic carbene (NHC) ligand had been successfully synthesized with reaction betw...
