摘　　要：碳硼化反应作为有机合成双官能化反应的策略之一,是合成各种天然产物、药物分子及精细化工产品重要的方法.对卤素阴离子催化的立体可控炔烃碳硼化反应进行了详细研究,通过卤素阴离子种类、用量、反应底物、溶剂、温度和时间等因素对反应活性、立体选择性的影响及其相互作用机制的探索,发展了一种高立体选择性地制备E式1,1-碳硼化物的新方法;相关研究表明,不同的Z、E构型碳硼化物作为催化剂,对环氧环己烷开环聚合的活性具有明显的差异.开展相关的立体可控碳硼化反应新方法的研究,不仅进一步拓展了烯基硼化物在有机双官能团转化反应中的应用,也对发展新型含硼有机化合物的研究与应用具有重要意义.The difunctionalization of alkenes and alkynes is a simple and powerful strategy for the synthesis of various organic compounds and has been used to synthesize various important natural products, drug molecules and fine chemical products. The different effects of halo anions, substrates, solvents, temperature and reaction time to the stereospecific and reactivities of 1,1-carboborations of alkynes and B(C6F5)s were studied, meanwhile the corresponding catalytic mechanisum has been expoled. A convenient large-scale preparation method for the stereoselective(E)-1,1-carboboration products has been developed. The catalytic reactivities of ring-opening polymerization of cyclohexene oxide(CHO) have also been explored with different stereo-carboboranes isolated from 1,1-carboboration reaction, and it is noted that the stereospecificity E-or Z-has shown ambiguously different activities. To develop a stereo-specific approach in the synthesis of vinylboranes will not only be very important for the difunctionalization of alkenes and alkynes, but also for the novel stereospecificity organoborons.
