The olefin metathesis reaction refers to a process of cutting and recombining a carbon-carbon heavy bond under metal catalysis. The olefin metathesis reaction is of great significance in polymer material chemistry and organic synthesis chemistry. The general formula of olefin metathesis reaction is shown in figure 1.

The olefin metathesis reaction is widely used in the chemical industry and is mainly used to develop drugs and advanced polymer materials.
Drug synthesis: Some scientists are using the method of olefin metathesis to develop new drugs for the treatment of cancer, Alzheimer's disease and AIDS.
Catalysts for olefin metathesis reactions can be classified into two categories: heterogeneous catalysts and homogeneous catalysts. Commercially available olefin metathesis reactions use heterogeneous catalysts.
1) Schrock catalysts: The Schrock catalyst is characterized by a molybdenum (VI)- and tungsten (VI)-based center supported by an alkoxide and an imino ligand.

2) Grubbs catalysts: The catalyst for Grubbs is a ruthenium (II) carotenoid complex. A portion of the chelatable isopropoxystyrene ligand is modified to form the associated Hoveyda-Grubbs catalyst.
