Abstract
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. A bout a 14% (v/v) solution of THF in the hydrocarbon provides an extent of metalation which exceeds that in neat THF at the same concentratio n. Impressive regioselectivity results from the DoM of p-MA in this so lvent system; virtually no metalation of the lateral methyl group occu rs.
