【摘要】 以2-羧甲基硫代烟酸为原料,水热法一步合成了一个新的噻吩并[2,3-b]吡啶类化合物——2-(3-噻吩并[2,3-b]吡啶基)-3-羟基噻吩并[2,3-b]吡啶,并通过单晶X-射线衍射实验、红外光谱等对其结构进行了表征.单晶X-射线衍射分析结果表明,该化合物属于单斜晶系,Pn空间群,a=1.225 76(4)nm,b=0.391 24(0)nm,c=1.354 28(5)nm,β=113.715(2)°,V=0.594 62(3)nm~3,Z=2,F(000)=294.运用逆合成分析法推测了由2-羧甲基硫代烟酸合成联二噻吩并[2,3-b]吡啶类化合物的反应机理.更多还原

【Abstract】 A new compound,2-(thieno[2,3-b]pyridin-3-yl)thieno[2,3-b]pyridin-3-ol,based on 2-carboxy-methylsulfanyl nicotinic acid was hydrothermally synthesized and characterized by single crystal X-ray diffrac-tion and IR spectrum.The compound was crystallized in monoclinic system with space group Pn,cell parame-ters of a=1.225 76(4)nm,b=0.391 24(0)nm,c=1.354 28(5)nm,β=113.715(2)°,V=0.594 62(3)nm~3,Z=2,F(000)=294.Using the inverse synthesis analysis,it was speculated on a mechanism for the reaction of 2-carboxymethylsulfanyl nicotinic acid synthesis of bis(dithieno[2,3-b]pyridine com-pounds,which would have potential application in synthesis of bis(dithieno[2,3-b]pyridine compounds and their derivatives.更多还原
