WitrynaBy prolonging the reaction time, the desired imine was converted into the corresponding secondary amine, N-phenylbenzylamine, with a remarkably high yield of 80% through the catalytic hydrogenation of the CN bond. Finally, we demonstrated that it was easy to reuse the catalyst up to five times. 展开 Witryna22 sie 2024 · The axial positions are coordinated by the imine nitrogen atom N4 and Cl2, which exhibits a small non-linearity [the N4–Co1–Cl2 bond angle is 171.61(13)°]. The N1–Co1–N2 bond angle is 77.4(2)°, and the N3–Co1–N4 bond angle is 76.76(18)°, which leads to a big block in Co1 metal center.
