Catalysts For Direct Conversion Of Ethylene To Propylene

Profs. Matthew P. Conley and Richard R. Schrock from the University of California, Riverside have developed a new catalyst that may be used to synthesize propylene from ethylene under mild conditions. The key steps involved in the direct conversion of ethylene to propylene are ring-contraction of a metallacyclopentane complex to a metallacyclobutane complex followed by rearrangement of the metallacyclobutane complex to propylene. This technology is advantageous because it consists of a single reaction overall that operates at mild temperatures, because the catalyst efficiency can be engineered to optimize turnover frequency and yield, and because propylene is the only product of the reaction.
