1,5-双(氯甲基)-2,4-二(丙-2-基)苯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 40.0 g (154 mmol) of the compound from Example 1 and 22.7 g (277 mmol) of sodium acetate are heated overnight at 80° C. in 200 ml of dimethylformamide. After distilling off the solvent, the residue is taken up with petroleum ether, washed with water and dried using sodium sulphate. After distilling off the solvent washed with water dried

反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 55 ml (0.46 mol) of tin tetrachloride are added dropwise with cooling in an ice bath (exothermic reaction) to a solution of 230 ml (2.43 mol) of chloromethyl ethyl ether and 197 g (1.22 mol) of 1,3-diisopropylbenzene in 600 ml of carbon tetrachloride and the mixture is stirred at 0° C. for 1 h. After stirring overnight at +25° C., 142 g (1.5 mol) of chloromethyl ethyl ether and 74 ml (0.46 mol) of tin tetrachloride are again added dropwise at 0° C. and the mixture is stirred overnight at +25° C. The reaction mixture is added to ice/hydrochloric acid, and the organic phase is separated off, washed with water and dried using sodium sulphate. After concentrating, the residue is taken up with petroleum ether, filtered through 1 kg of silica gel (230-400 mesh) and distilled in a high vacuum. with cooling in an ice bath After stirring overnight at +25° C. the mixture is stirred overnight at +25° C the organic phase is separated off washed with water dried After concentrating filtered through 1 kg of silica gel (230-400 mesh) distilled in a high vacuum
