Abstract

The magnesiation of halogenated aromatic and heteroaromatic carboxylic acids is accomplished by their treatment with MeMgCl in the presence of LiCl and subsequent reaction with i-PrMgCl·LiCl; the resulting double-magnesiated species react with a variety of electrophiles in up to 97% yield.
