Photochemistry of ReR(CO)3(Pri-dab)(R = Me, Et, Bn; dab = 1,4-diazabuta-1,3-diene): homolysis of the Re–R bond, its dependence on R and evidence for the reactive σbπ* state from transient absorption spectra
摘要:
从量子产额和纳秒闪光光解数据以及UV-PE光谱中可以得出结论,只有当R = Et或Bn时,ReR(CO)3(Pri-dab)(R = Me, Et, Bn)复合物的金属-配体电荷转移(MLCT)激发才会导致金属-烷基键的高效均裂解,此时反应性Ψb*状态与MLCT状态的能量接近。
