Lithiation of tris(benzotriazol-1-yl)methane 16 gives the tris(benzotriazolyl)methyl carbanion 17 which affords substitution products 18 with many electrophiles. Acidic hydrolysis of 18 affords the corresponding carboxylic acids 19 in good yield. The syntheses of several α-functionalized carboxylic acids are described.
