実験手順

One mole of cyanuric chloride was treated with one mole of phenylmagnesium bromide as described in Step I of Example I. The product of this reaction (2.3 g, 0.01 mole) in 25 ml of tetrahydrofuran (THF) was added slowly to a refluxing solution of the Grignard reagent prepared from 1-(trimethylsilyl)-2-(4-bromophenyl)acetylene (0.03 moles) and magnesium (0.75 g). The solution was stirred overnight, filtered, and the solvent removed. To the residue which remained was added a solution of KOH (10.0 g) in water (5 ml), anhydrous ethanol (100 ml) and dioxane (100 ml). The resulting mixture was heated for 2.5 hours at 60° C., filtered, and the solvent removed. Chromatographic separation of the resulting residue yielded a yellow solid, 6-phenyl-2,4-bis(4-ethynylphenyl)-s-triazine, which melted at approximately 215° C. with rapid polymerization.
