Definition

Adlhart and Chen found that ligand rotation is the difference between the activity of the first and second-generation Grubbs catalysts. This difference is brought about by a difference in the symmetry of the ligands. The phosphine ligand has a threefold symmetry, which causes a high barrier in the middle of the reaction coordinate, which is forced by the need for rotation of the phosphine. However, the barrier is absent for the second-generation Grubbs catalyst, with twofold symmetry of the NHC ligand. The rate-limiting step for second-generation catalysts is always phosphine dissociation[2].
