高效Ni/Zn催化剂体系固定CO_2与环氧化合物的环加成反应

An Efficient Ni/Zn Catalyst System for the Chemical Fixation of CO_2 with Epoxides

在15MPaCO2,100℃下NiCl2/bipy/Zn/TBAB催化剂体系能够高效、无溶剂地催化固定二氧化碳和环氧化合物的环加成制备环状碳酸酯的反应,得到了很高的催化收率和转化频率.并且在该催化剂体系中第一次得到了全顺式的环氧环己烷的碳酸酯.

The synthesis of cyclic carbonates from epoxides and carbon dioxide catalyzed by NiCl2/bipy/Zn/TBAB catalyst system without any solvent was achieved in excellent selectivity and TOF at 1.5 MPa, 100 degreesC. Pure cis-cyclohexene carbonate was firstly obtained in this catalytic system.
