of [n]staffanes (the oligomers of [1.1.1]propellanen=1-5) functionalized on one or both ends is described,and their properties are summarized. The substituents are -COOCH 3 ,-n-C 4 H 9 ,-C 6 H 5 ,-Br,-I and -SCOCH 3 , and their conversion to others,such as -COOH, -COCH 3 and -SH,is demonstrated. it is proposed that these rod-shaped molecules will be useful in the development of a molecular-size civil
描述了一种在一端或两端官能化的 [n]staffanes([1.1.1]propellane 的低聚物 n=1-5)的简便但低场合成,并总结了它们的性质。取代基为-COOCH 3 、-nC 4 H 9 、-C 6 H 5 、-Br、-I 和-SCOCH 3 ,并证明了它们向其他取代基如-COOH、-COCH 3 和-SH 的转化。建议这些棒状分子将有助于开发类似于儿童玩具建筑套装的分子大小的土木工程建筑套装

and unsymmetrically substituted 1,3-bissulfanylbicyclo[1.1.1]pentanes from disulfides and [1.1.1]propellane. Bicyclo[1.1.1]pentanes (BCPs) recently gained interest as rigid linkers and as bioisosters of para-substituted benzene and alkyne moieties. The most promising precursor for BCPs is [1.1.1]propellane (1). The available methods to synthesize BCPs are quite limited and many groups contribute to the
