Novel tetramers of 1,3-adamantane and 5,7-dibutyl-1,3-adamantane were synthesized by the coupling reaction of 3-bromo-1,1′-biadamantane or 3-bromo-5,5′,7,7′-tetrabutyl-1,1′-biadamantane with sodium in n-octane or with magnesium in diethyl ether. Although the former 1,3-adamantane tetramer showed poor solubility in organic solvents, the latter tetrameric 5,7-dibutyl-1,3-adamantane was readily soluble
通过3-溴-1,1'-双金刚烷或3-溴-5,5',7,7的偶联反应合成了1,3-金刚烷和5,7-二丁基-1,3-金刚烷的新型四聚体'-四丁基-1,1'-双金刚烷,含正辛烷中的钠或含镁的二乙醚。尽管前者1,3-金刚烷四聚体在有机溶剂中的溶解度较差,但后者四元5,7-二丁基-1,3-金刚烷易溶于THF,氯仿和苯,并已通过NMR,IR,SEC和NMR进行了成功表征元素分析。
