The reliable and efficient generation of carbon-carbon bonds underpins the foundation of chemical synthesis. Of these, olefin metathesis has risen to the forefront of the methods utilized for the preparation of alkenes. Catalyst developments in the past 25 years have dramatically increased the accessibility of this reaction for general use, with many catalysts now being commercially available. In addition, significant progress has been made in understanding the catalyst and substrate structural features, their interactions, and experimental conditions crucial to reaction selectivity. This has led to numerous applications of olefin metathesis in both academia and industry. In particular, cross-metathesis, ring-closing metathesis, enyne metathesis, ring-rearrangement metathesis, as well as tandem processes, remain highly active areas of investigation.
Despite the progress that has been achieved, many challenges remain, principally with regard to catalyst stability and control. The issue of control manifests itself in a myriad of ways, be it regiochemical or stereochemical. For example, the issue of olefin diastereocontrol in metathesis remains a significant challenge due to the thermodynamic nature of the reaction. Additionally, the pursuit of substrate control, while maintaining high catalyst turnover numbers in the face of steric and electronic impediments, remains a significant goal of catalyst design. Fortunately, recent years have seen many elegant solutions towards progress in overcoming these hurdles.
This Special Issue on olefin metathesis will offer an attractive forum to present recent results in olefin metathesis pertaining to catalyst development, broadened substrate scope and/or stereocontrol, as well as the application of olefin metathesis to synthesis. I strongly encourage authors to submit papers for Molecules’ Special Issue on Olefin Metathesis. I believe that the topics covered will thoroughly convey the expanding potential and applicability of this versatile reaction.
