Aromatic and heterocyclic 2,2-dialkylhydrazides undergo directed metalation with 2 equivalents of n-, s- or t-BuLi, and the resulting C,N- dilithio species react with a variety of electrophiles. The products may be readily converted to the corresponding carboxylic acids or esters by oxidation with manganese dioxide in water or methanol containing acetic acid.
