Reaktionsschritte
7.75 g (30 mmol) of 1,1,1,3,3,3-hexafluoro-2-p-tolylpropan-2-ol were dissolved in 45 ml of DMF, and 1.2 g (40 mmol) of NaH (80% strength dispersion in mineral oil) were added. After a clear solution had formed, 5.0 g (14 mmol) of 2,4,6-trimethylbenzene-1,3-disulfonyl chloride were added and the mixture was stirred for a further 72 hours at room temperature. The mixture was poured into water and the precipitated product was filtered off and dried. 7.8 g of 1,3,5-trimethyl-2,4-bis-(2,2,2-trifluoro-1-p-tolyl-1-trifluoromethylethoxy-sulfonyl)-benzene were obtained (colorless crystals, m.p.: 178° C. [from acetonitrile]).
