351498-10-7, 6,6′-((1E,1’E)-((2,3-Dimethylbutane-2,3-diyl)bis(azanylylidene))bis(methanylylidene))bis(2,4-di-tert-butylphenol) is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

N,N-Bis(3,5-di-tert-butylsalicylidene)-1 ,1 ,2,2-tetramethylethylenediamine (24, 0.73 g, 1 .3 mmol)was suspended in 10.0 mL of ethanol. The resulting suspension was heated to 80 c and stirred for 5minutes under argon balloon. Cobalt (II) acetate (0.24g, 1 .3 mmol) was then added, and the reactionmixture was stirred for another 2 hours at 80 00. The crimson red suspension was cooled down to roomtemperature in an ice bath and was filtered. The collected red solid was dried under vacuum to provide0.70 g of compound 25 (87%).

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.351498-10-7,6,6′-((1E,1’E)-((2,3-Dimethylbutane-2,3-diyl)bis(azanylylidene))bis(methanylylidene))bis(2,4-di-tert-butylphenol),as a common compound, the synthetic route is as follows.

Compound Int-1a (733 mg, 1.33 mmol) was suspended in ethanol (10 mL) and the resulting suspension was heated to 80 C and allowed to stir for 5 minutes. Compound Int- 1b (236 mg, 1.33 mmol) was then added and the resulting reaction was allowed to stir at 80 C for an additional 2 hours. The reaction was then cooled to room temperature using in an ice bath and the reaction mixture was filtered. The collected red solid was dried under vacuum to provide compound Int-1c (579 mg, 72%).

A 50 mL flask was charged with N,N?-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(II) complex.
