Yang, Jin published the artcile(N-heterocyclic carbene)PdCl(N-heterocyclic carboxylate) complexes: Synthesis and catalytic activities towards arylation of benzoxazoles with aryl halides, Name: 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride, the publication is Applied Organometallic Chemistry (2018), 32(7), n/a, database is CAplus.
A series of N-heterocyclic carboxylate-stabilized N-heterocyclic carbene palladium complexes has been synthesized and fully characterized. The solid-state structures indicate that each of the palladium centers is coordinated by an N-heterocyclic carbene, a chloride and a bidentate N,O-donor N-heterocyclic carboxylate ligand. The catalytic performance of the complexes was screened and the results revealed that the complexes exhibit moderate to high catalytic activities for the direct C-H bond arylation of benzoxazoles with aryl bromides.
Applied Organometallic Chemistry published new progress about 258278-25-0. 258278-25-0 belongs to imidazoles-derivatives, auxiliary class Achiral NHCs Ligands, name is 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride, and the molecular formula is C15H12O8, Name: 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride.
