It is a common heterocyclic compound, the chiral-catalyst compound, 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 its synthesis route is as follows.,351498-10-7
Preparation of Cobalt(ll) Complex used in Step 2: A 50 mL flask was charged with lambda/,lambda/-bis(3,5-di-tert-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(ll) complex.
With the complex challenges of chemical substances, we look forward to future research findings about 6,6′-((1E,1’E)-((2,3-Dimethylbutane-2,3-diyl)bis(azanylylidene))bis(methanylylidene))bis(2,4-di-tert-butylphenol)
