Katritzky, Alan R.,Yang, Zhijun,Lam, Jamshed N.

, p. 666 - 669 (2007/10/02)

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.
