合成了７，１１－二硒杂苯并－１３－冠－４及其铂配合物，并从底物的性质、反应温度、催化剂用量以及化学气氛四个方面考察了该配合物对烯烃与三乙氧基硅烷的硅氢加成反应的催化特性。与单硒杂冠醚配合物相比，该配合物对某些烯烃的催化活性较高，但催化反应需要的温度也较高． Synthesis of 7,11-diselenobenzo-13-crown-4 and its platinum complexes, and from the substrate properties, reaction temperature, the amount of catalyst and the chemical atmosphere investigated four aspects of the complex on the olefin and tris Catalytic properties of hydrosilylation of ethoxysilane. Compared with the monounsaturated crown ether complex, the complex has high catalytic activity for some olefins, but the catalytic reaction also requires higher temperatures.
