On October 1, 2018, Nesterova, Oksana V.; Nesterov, Dmytro S.; Jezierska, Julia; Pombeiro, Armando J. L.; Ozarowski, Andrew published an article.Synthetic Route of 2160-93-2 The title of the article was Copper(II) Complexes with Bulky N-Substituted Diethanolamines: High-Field Electron Paramagnetic Resonance, Magnetic, and Catalytic Studies in Oxidative Cyclohexane Amidation. And the article contained the following:
The novel coordination compounds [Cu2(HtBuDea)2(OAc)2] (1) and [Cu2(HBuDea)2Cl2]·nH2O (2) have been prepared through the reaction of the resp. copper(II) salts with N-tert-butyldiethanolamine (H2tBuDea, for 1) or N-butyldiethanolamine (H2BuDea, for 2) in methanol solution Crystallog. anal. reveals that, in spite of the common binuclear {Cu2(μ-O)2} core, the supramol. structures of the complexes are drastically different. In 1 binuclear mols. are linked together by H-bonds into 1D chains, while in 2 the neighboring pairs of binuclear mols. are H-bonded, forming tetranuclear aggregates. Variable-temperature (1.8-300 K) magnetic susceptibility measurements of 1 and 2 show a dominant antiferromagnetic behavior. Both complexes were also studied by HF-EPR spectroscopy. While the interaction between Cu(II) centers in 1 can be described by a single coupling constant J = 130.1(3) cm-1 (using H = JS1S2), the crystallog. different {Cu2(μ-O)2} pairs in 2 are expected exchange from ferro- to antiferromagnetic behavior (with J ranging from -32 to 110 cm-1, according to DFT calculations). Complexes 1 and 2 act as catalysts in the amidation of cyclohexane with benzamide, employing tBuOOtBu as oxidant. The maximum achieved conversion of benzamide (20%, after 24 h reaction time) was observed in the 1/tBuOOtBu system. In the cases of tBuOO(O)CPh or tBuOOH oxidants, no significant amidation product was observed, while for tBuOO(O)CPh, the oxidative dehydrogenation of cyclohexane occurred, giving cyclohexene, to afford the allylic ester (cyclohex-2-en-1-yl benzoate) as the main reaction product. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Synthetic Route of 2160-93-2
