Upon treatment of cyclic 1,2-bis(silylethynyl)benzenes with lithium naphthalenide, the intramolecular reductive cyclization proceeds in an endo–endo mode to produce 1,4-dilithio-2,3-disilylnaphthalenes, which are transformed into a series of 1,4-difunctionalized 2,3-disilylnaphthalenes.
用萘化锂处理环状 1,2-双(甲硅烷基乙炔基)苯后,分子内还原环化以内-内方式进行,产生 1,4-二硫代-2,3-二甲硅烷基萘,其转化为一系列 1 ,4-双官能化的 2,3-二甲硅烷基萘。
