Hemiperoxyacetals derived from 2,3-dimethylbut-1-en-3-yl hydroperoxide and aliphatic aldehydes undergo cyclisation with NIS or NBS to afford the corresponding 3-alkyl-5-halogenomethyl-5,6,6-trimethyl-5,6,6-trimethyl-1,2,4-trioxanes in yields of 20–65%
衍生自2,3-二甲基丁-1-烯-3-基氢过氧化物和脂族醛的半过氧
缩醛与NIS或
NBS进行环化反应,得到相应的3-烷基-5-卤代甲基-5,6,6-三甲基-5,6, 6-三甲基1,2,4-
三恶烷的产率为20–65%
