Extracurricular laboratory: Synthetic route of 351498-10-7

6,6′-((1E,1’E)-((2,3-Dimethylbutane-2,3-diyl)bis(azanylylidene))bis(methanylylidene))bis(2,4-di-tert-butylphenol), cas is 351498-10-7, it is a common heterocyclic compound, the chiral-catalyst compound, its synthesis route is as follows.,351498-10-7

Cobalt catalyst 1 was prepared as follows: A 50 mL flask was charged with lambda/,/V’-bis(3,5-di-fert-butylsalicylidene)-1 ,1 ,2,2-tetramethylethenediamine (0.4302 g, 0.78 mmol, 1.0 equiv), EtOH (17 mL), and Co(OAc)2 (0.1385 g, 0.78 mmol, 1.0 equiv). The mixture was degassed and then heated to reflux under nitrogen for 3 h, cooled to room temperature. The precipitate was filtered and the purple solid was washed with EtOH (10 mL) and dried under high vacuum to give 0.3533 g (75%) of the cobalt(l I) complex. LC-MS Method 2 tR = 1.921 min, m/z = 440.1 ; 1H NMR (CD3OD) delta=1.25 (s, 3H), 1.49 (s, 3H), 2.04 (d, 3H), 2.34 (m, 2H), 2.38 (m, 1 H), 2.40 (m, 2H), 3.02 (m, 1H), 5.67 (m, 1 H), 6.97 (m, 2H), 7.26 (m, 3H), 7.38 (m, 4H).

As the rapid development of chemical substances, we look forward to future research findings about 351498-10-7
