(2,3-dimethoxyphenyl)acetylene (1) and 7-bromo-8-methoxyquinoline (2), followed by reduction of the alkyne and final ether cleavage. The unsymmetric type II triple-stranded dinuclear helicate M3[Ga2(7)3] (M=Na, K) is obtained with gallium(III) ions in the presence of potassium or sodium carbonate.
乙烯连接的邻苯二酚/ 8-羟基喹啉衍生物7-H 3 通过三步法,通过Sonogashira-Hagihara偶联(2,3-二甲氧基苯基)乙炔(1)和7-溴-8-甲氧基喹啉(2)制备,然后还原炔烃并最终裂解醚。在碳酸钾或碳酸钠的存在下,镓(III)离子可得到不对称的II型三链双核螺旋盐M 3 [Ga 2(7)3 ](M = Na,K)。
