本文按树枝状大分子骨架的化学结构分类，对侧链型树枝状大分子液晶的设计合成、液晶相行为及其自组织超结构的最新研究进展进行总结和评述，重点介绍了聚酰胺-胺、聚丙烯亚胺、聚碳硅烷、聚醚以及聚酯树枝状大分子液晶体系。

A base-catalyzed novel olefination methodology based on elimination of p-toluenesulfonamide:Treatment of diethyl cyanomethylphosphonate with catalytic amount of basegave the corresponding phosphoryl-stabilized carbanion, which added to the carbon-nitrogen double bond of N-tosyl imines.

新形成的氮负离子进一步攫取另一分子膦酸酯的活泼亚甲基氢形成加成产物同时再生出膦酰基稳定的碳负离子。加成产物消除对甲苯磺酰胺，高度立体选择性地得到-α-氰基-β-芳基-乙烯基膦酸二乙酯。
