中文摘要:
      以2,2′-二羟基联苯为原料,经过羟基保护、羟基邻位甲酰化、去保护等反应,合成了2,2′-二羟基-[1,1’-联苯基]-3,3′-二醛,再与2-丙硫基苯胺通过希夫碱反应合成了一种新型的双水杨醛亚胺配体3,3′-双-[(2-丙硫基)-苯亚胺]-2,2′-二羟基联苯(5).所合成的化合物通过核磁氢谱、元素分析、红外光谱等手段进行了表征,目标产物5通过X射线单晶衍射进一步证实了其结构.双水杨醛亚胺配体5晶体结构表明两个相连的苯环不共平面,二面角为63.14°,且两个水杨醛亚胺中配位原子所在的键长、键角不同,说明与中心金属配位时产生了两个不同的活性中心.
英文摘要:
      2,2′-dihydroxy-[1,1’-biphenyl]-3,3′-dicarbaldehyde was synthesized by hydroxyl protection, ortho formylation and deprotection reactions with 2,2′-dihydroxybiphenyl as starting material, followed by reaction with 2-propylthio aniline to obtain a new biphenol diimine ligand named 3,3′-bis-[(2-propylthio)-phenylimino]-2,2′-dihydroxybiphenyl (5). All the compounds were characterized by 1H NMR, FTIR, and elemental analysis. The ligand 5 was further characterized by X-ray single crystal diffraction, which indicated that the two linked phenyl rings were not coplanar, with a dihedral angle of 63.14°. The bond lengths and bond angles around the coordination atoms on two salicylaldimine were also different, suggesting that two different active centers may exist when coordinated with metals.
