Description

CO2 is a greenhouse gas for which reduction in atmospheric levels is a current imperative. Commonly we think of reducing emissions or removing and CO2 in sequestration. An attractive alternative would be to use CO2 as a chemical feedstock and the production of cyclic carbonates offers one approach to this. In this work we have used a combined experimental/theory methodology to look at the addition of CO2 to epoxides formed from cyclic alkenes. We show how the reactivity of the epoxides to form carbonates depends on the ring size of the cyclic alkene. Mechanistic insight has been obtained from DFT calculations using the Gaussian programme with the B3LYP functional and a 6-31G(d,p) basis set. The resulting structures are deposited here and indexed according to the mechanism presented in the publication. The data is stored as Materials Studio .car files which contains the element type and x,y,z co-ordinates of all atoms in a simple format.
