Stibatriptycene (1c) has been synthesized by cyclization of 9-(o-chlorophenyl)-9,10-dihydro-9-stibaanthracene (2c) with an excess of lithium piperidide. The general applicability of this ring closure reaction, first developed for the synthesis of phosphatriptycene (1a) and presumed to proceed by nucleophilic attack of a carbanionic centre on a (slowly generated) benzyne, has further been demonstrated
通过将9-(邻氯苯基)-9,10-二氢-9-stibaanthracene(2c)与过量的哌啶锂进行环化反应,合成了三苯并噻吩(1c)。该闭环反应的普遍适用性首先是为合成磷酸三苯并(1a)而开发的,推测是通过碳负离子中心在(缓慢生成的)苯并苯上的亲核攻击而进行的,而这种新的已知的三苯并噻吩的合成又进一步证明了该反应的普遍适用性。 (1b)和由stitriptriptycene合成(1c)。1c的结构通过IR,1 H NMR,特别是通过13 C NMR光谱法确认。
