Методика

Synthesis based on literature procedure (Gates, D. P.; Svejda, S. A. Onate, E.; Killian, C. M.; Johnson, L. K.; White, P. S.; Brookhart M. Macromolecules, 2000; 33:2320-2334.). Cyclohexane-1,2-dione (2.062 g, 18.39 mmol) and 2,6-diisopropylaniline (6.52 g, 36.78 mmol) are dissolved in 70 mL of methanol. To this solution is added 1 mL of formic acid and the mixture is stirred for 3 days at room temperature. Precipitated white crystalline solid is collected on the frit, washed with methanol (2×15 mL) and dried under reduced pressure to give 4.1 g (51.8% yield) of title compound of Preparation 1.
