The reaction between -butyllithium and 1-bromobicyclo[1.1.1]pentane is characterised by 1,3-dehydrobromination and gives [1.1.1]propellane . In the presence of -butyllithium, undergoes ring-opening and yields 3--butylbicyclo[l.l.1]pentyllithium .
-丁基锂与1-溴二环[1.1.1]戊烷之间的反应的特征在于1,3-脱氢溴化,得到[1.1.1]丙炔。在-丁基锂的存在下,进行开环并产生3--丁基双环[III]戊基锂。
