with synthesis of 2-acetyl-5-bromopyridine (3) from 2,5-dibromopyridine, substitution of the bromine in 3 using a variety of metal-catalyzed reactions and then formation of the terpyridine using the Krohnke reaction. The complexes have been prepared by reaction of [Pt(PhCN)2Cl2] with the appropriate silver salt followed by addition of the terpyridyl ligand. The crystal structure of two complexes have
描述了三取代的4',5,5''三联吡啶的合成。该战略始于综合2-乙酰基5-溴吡啶(3)从2,5-二溴吡啶,替代 溴在3使用各种金属催化反应,然后形成特吡啶使用克罗恩克反应。配合物是通过[铂(PhCN)2 Cl 2]与适当的银盐,然后加入 联吡啶配体。两种配合物的晶体结构已通过X射线衍射确定,而MLCT(金属至配体电荷转移)发射已通过UV / Vis光谱确定。
