Syntheses, Structures, and O<sub>2</sub>-Reactivities of Copper(I) Complexes with Bis(2-pyridylmethyl)amine and Bis(2-quinolylmethyl)amine Tridentate Ligands
converted to the copper(I) complexes without having any ancillary ligands in order to examine their O 2 -reactivity. Significantly large differences in O 2 -reactivity were found among the copper(I) complexes. On the basis of 02-reactivity together with the X-ray structures and the oxidation potentials of the copper(I) complexes, the stericeffects of the hetero-aromatic donor groups (6-substituted pyridine
由双[(6-苯基-2-吡啶基)甲基]胺三齿配体(L5 R )和双(2-喹啉甲基)胺三齿配体(L6 R )支持的铜(I)配合物的结构和O 2 -反应性具有为了深入了解三齿配体对铜(I)/O 2 化学的空间效应,进行了详细研究。在苄胺和苯乙胺衍生物 [R = -CH 2 Ph (Bz) 和 -CH 2 CH 2 Ph (Phe)] 的情况下,配体与 [Cu I (CH 3 CN) 4 ] + 之间的反应得到相应的铜(I)-乙腈配合物具有扭曲的四面体几何形状。另一方面,2,2-二苯乙胺衍生物 L6 R [R = -CH 2 CHPh 2 (PhePh)] 提供了没有辅助配体 (CH 3 CN) 的铜 (I) 配合物,并且在铜 (I) 离子和烷基取代基 PhePh 的苯基。然后通过与 CO 气体反应将乙腈络合物转化为相应的 CO 络合物。已确定所有 CO 配合物的 X 射线结构,并且配合物具有类似的扭曲四面体几何形状。此外,L5
