Rates and extents of directed ortho metalation (DoM) of anisole and p-methylanisole (p-MA) with n-BuLi have been measured in THF/n-hexane. About a 14% (v/v) solution of THF in the hydrocarbon provides an extent of metalation which exceeds that in neat. THF at the same concentration. Impressive regioselectivity results from the DoM of p-MA in this solvent system; virtually no metalation of the lateral methyl
率和定向的程度邻位金属化的苯甲醚(DOM)和p -methylanisole(p -MA)与ñ正丁基锂已在THF被测量/ Ñ己烷。烃中约14%(v / v)的THF溶液提供的金属化程度超过纯金属化程度。相同浓度的THF。令人印象深刻的区域选择性是由该溶剂系统中p -MA的DoM引起的。实际上,没有发生侧甲基的金属化。
