实验步骤: To a solution of 2.142 g (15.96 mmol) of 4-(2-propenyl)phenol (prepared as in Example 1) in 15 mL of methylene chloride was added 2.351 g (22.19 mmol) of cyanogen bromide (Aldrich). The mixture was cooled in an ice-salt bath and 3 mL (22 mmol) of triethylamine was added dropwise with stirring. The mixture was stirred for an additional 15 minutes. The solvent was removed under vacuum and the mixture was transferred to a separatory funnel with 25 mL of water and 75 mL of petroleum ether (30-60° C. boiling range). The aqueous and organic layers were separated. The organic layer was washed with three 50 mL portions 6 N hydrochloric and one 50 mL portion of saturated sodium bicarbonate, dried over anhydrous magnesium sulfate, and filtered. The solvent was removed under vacuum to yield 1.668 g (66%) of crude 1-cyanato-4-(2-propenyl)benzene. The product was distilled to yield 1.307 g (51%) of 1-cyanato-4-(2-propenyl)benzene. The structure of the product was verified by IR and NMR spectroscopy. The product can be further purified by passing the product through a silica gel column using 1% toluene in petroleum ether as the solvent system.

实验步骤: To 50.01 g (337.4 mmol) of 1-methoxy-4-(2-propenyl)benzene (Aldrich Chemical Company, Milwaukee, Wis.) dissolved in 300 mL of anhydrous methylene chloride was added dropwise 375 mL (375 mmol) of 1.0 M boron tribromide (Aldrich) in methylene chloride. The reaction was run under nitrogen at room temperature and the mixture was stirred for 1 hour. The mixture was poured over 1000 mL of crushed ice, stirred for 5 minutes, and transferred to a separatory funnel. The organic layer was drained and saved. The boron salts were transferred to a filter containing Celite™ (Aldrich Chemical Co., Milwaukee, Wis.) and the filter containing the salts was washed with portions of methylene chloride and then water. The filtrate was transferred to a separatory funnel and the organic and aqueous layers were separated. The aqueous layer was extracted with four 100mL portions of methylene chloride. The methylene chloride solutions were pooled, dried over anhydrous magnesium sulfate, and filtered. The solvent was removed under vacuum to yield 25.27 g (56%) of crude 4-(2-propenyl)phenol. The crude product was distilled twice at reduced pressure to yield 20.34 g (45%) of 4-(2-propenyl)phenol. The NMR data was consistent with that reported by Rajashekhar and coworkers (J. Biol. Chem. 1984, 259, 6925). was run under nitrogen at room temperature stirred for 5 minutes transferred to a separatory funnel containing Celite™ (Aldrich Chemical Co., Milwaukee, Wis.) the filter containing the salts was washed with portions of methylene chloride The filtrate was transferred to a separatory funnel the organic and aqueous layers were separated The aqueous layer was extracted with four 100mL portions of methylene chloride dried over anhydrous magnesium sulfate filtered The solvent was removed under vacuum
