专利号:US-5919992-A 优先权日:1996-06-11 标 题:Synthesis of haloalkynol 发明人:KUO DAVID L 权利人:LONZA AG 摘要:The present invention relates to process of halogenating an alkynol having 3 to 20 carbon atoms to produce a compound having the formula: R-C 3BOND (C-CH2)x-OH, wherein R is F, Cl, Br or I and x is 1 to 18. In particular, this invention provides a process for preparing a halopropynyl alcohol, specifically iodopropynyl alcohol. In one embodiment, iodopropynyl alcohol is produced by sequentially adding potassium hydroxide, potassium iodide and an oxidizing agent to a solution of propynyl alcohol at a rate and temperature sufficient to produce an iodopropynyl alcohol.
