• Reagent for carboxyl protection as phenacyl esters, stable to acid hydrolysis but readily cleaved by nucleophiles or by reduction. See Appendix 6. Protection can be effected in the presence of triethylamine: J. Chem. Soc. (C), 1191 (1966), or, better, KF in DMF: Tetrahedron Lett., 599 (1977). Phase-transfer conditions have also been reported: Synth. Commun., 26, 1747 (1996). Cleavage has been described using a variety of reagents, including Zn-AcOH: Tetrahedron Lett., 343 (1970), catalytic hydrogenolysis, treatment with PhS-, PhSeH, or NaHTe: Synth. Commun., 18, 116 (1988); TBAF: J. Org. Chem., 56, 5465 (1991); or photolysis: J. Org. Chem., 62, 6245 (1997).

• 可燃性危险特性:明火可燃; 受热分解有毒溴化物气体
• 方法一:由苯乙酮溴化而得。将水、苯加入反应锅中，搅拌，在25℃迅速加入溴素，缓缓升温至55-60℃，反应10-20min，加入冰水，冷至0-5℃，甩滤，滤饼用冰水洗涤，甩干，即得溴苯乙酮。收率92%。上述反应过程中，反应锅内能发出闷雷般的响声。也可以使苯乙酮在乙醚溶剂中滴加溴素反应，并用在反应液中加入无水三氯化铝。此法以88-96%的产率获得粗品。另外，苯乙酮与溴在三氧化二铝存在下作用亦可制得，收率94%。
