실험 절차

BF3 is passed for 30 minutes into a mixture of 84 parts by weight of 2-methyl-3-phenyl-propyl chloride and 50 ml of BF3 ·2H2O at room temperature. 56 parts by weight of tert.-butyl chloride are then added dropwise at room temperature. The mixture is refluxed for 4 hours and is then allowed to cool; the crude product is introduced into water and extracted with chloroform. The organic phase is separated off, washed with water, dried over Na2CO3 and distilled. 30 parts by weight of 2-methyl-3-phenyl-propyl chloride, boiling point 105° C./16 mm Hg, and 45 parts by weight of 2-methyl-3-(p-tert.-butylphenyl)-propyl chloride, boiling point 80° C.-81° C./0.02 mm Hg, are obtained.
