Product Description

peculiarity
The second generation of Grubbs catalyst is to replace the tricyclohexylphosphine ligand in the first generation catalyst with a di-substituted dihydroimidazole ligand. Due to the steric and electronic effects of nitrogen substituents in the ligand, Grubbs second-generation catalysts are relatively stable during the reaction and are not easy to decompose themselves. Compared with the first generation catalyst, it has stronger stability and higher reactivity. The design concept of Grubbs II catalysts is to replace one of the phosphorus ligands with an N-heterocyclic carbene ligand, which has stronger electron-giving ability and higher stability than the phosphorus ligand.
