摘要： The present disclosure provides a use of a catalyst for catalyzing a reaction of an epoxide compound and carbon dioxide, the catalyst includes a spirocyclic compound including at least one compound of formula (1):




where X is selected from nitrogen, or phosphorus; Y is selected from halogens; A and B are independently selected from materials having formulae (a) to (d). Compared with catalysts with a non-spirocyclic structure or Lewis acid metal catalysts, the catalyst including the spirocyclic compound having the structural shown in formula 1 has the advantages of better catalytic effect, more stable performance and longer service life when catalyzing the reaction of the epoxy compounds and carbon dioxide. The present catalyst has both high efficiency and safety, and thus has broad application prospects.

摘要： A method for catalyzing a reaction of an epoxide compound and carbon dioxide with a catalyst. The catalyst comprises at least one compound of formula (1):






where R is selected from an alkyl group, an alkenyl group, a halohydrocarbyl group, an aromatic hydrocarbyl group, an imidazolyl group, or a heteroaromatic hydrocarbyl group; X is selected from halogens; B is selected from nitrogen, or phosphorus; A is selected from any of the following formulae with a sign * representing a bonding position:
