This study reports on Re tricarbonyl complexes bearing 8-(diphenylphosphanyl)quinoline, P∩N, and 8-(diphenylarsanyl)quinoline, As∩N, as bidendate ligands. We studied the reactivity of these complexes in comparison with fac-Re(N∩N)(CO)3Cl (with N∩N = 2,2′-bipyridine or 4,4′-dimethyl-2,2′-bipyridine). We used a combination of electrochemical and spectroelectrochemical methods with time-resolved spectroscopy
本研究报告了带有 8-(二苯基膦基)喹啉 (P∩N) 和 8-(二苯基胂基)喹啉 (As∩N) 作为双齿配体的 Re 三羰基配合物。我们研究了这些配合物与fac -Re(N∩N)(CO) 3 Cl(其中 N∩N = 2,2′-联吡啶或 4,4′-二甲基-2,2′-联吡啶)的反应性。我们将电化学和光谱电化学方法与超过 10 个数量级 (100 ps–1 s) 的时间分辨光谱相结合,研究了单电子还原的 Re(CO) 3 (P∩N)Cl 和 Re的特殊反应性。(CO) 3 (As∩N)Cl 络合物也在质子存在下形成。
