We report herein an efficient synthesis of a series of chelating bis(aryloxide) ligands that can be diverged at a late stage to generate a variety of structures. Based on structural differences between linked and unlinked analogs of six-coordinate acid–base adducts of (ArO)2TiCl2(dmpe), a hypothesis predicted that a difference between the two structure types would be apparent when the compounds shuttled
我们在本文中报道了一系列螯合双(芳氧基)配体的有效合成,该配体在后期可以分开以产生多种结构。根据(ArO)2 TiCl 2(dmpe)六配位酸基加成物的链接和未链接类似物之间的结构差异,一种假设预测,当化合物在四键和六键之间穿梭时,两种结构类型之间的差异将很明显。六坐标结构。比较它们在路易斯酸中的效率会加速Diels-Alder反应,但并不支持这一观点。
