B(C6F5)3在有机化学及高分子化学中的应用研究进展

B(C6F5)3与传统的Lewis酸相比,具有化学性质稳定、酸性强、使用方便等优点,被称为非传统的Lewis酸。B(C6F5)3的应用领域已经从最初的烯烃聚合共催化剂向有机化学及高分子化学的其它各个领域发展。B(C6F5)3催化的反应与传统Lewis酸催化的反应在反应机理及反应结果上均有很大的不同。本文主要综述B(C6F5)3近年来在有机化学及高分子化学中的应用研究成果。

Application of Tri(pentafluorophenyl)borane in Organic Chemistry and Polymer Chemistry

Compared with traditional Lewis acid,B(C_6F_5)_3 was more stable in moisture and air,easier handled with strong Lewis acidity,and it was called nontraditional Lewis acid. The application of B(C_6F_5)_3 has been extended from cocatalyst of olefin polymerization to many other fields in organic chemistry and polymer chemistry. The mechanism and the results of the reaction catalyzed by B(C_6F_5)_3 were different from analogous reaction catalyzed by traditional Lewis acid such as AlCl_3. The progress of application of B(C_6F_5)_3 in organic chemistry and polymer chemistry was reviewed, including reduction of alcohol,reduction of carbonyl,olefin polymerization, allylation of secondary benzyl alcohol and its derivatives,allylation of propargyl acetates,reduction of phosphonic and phosphic esters,preparation of polysiloxane copolymers from alkoxysilanes and organohydrosilanes.
