The Carboxylic Acid Group as an Effective Director of Ortho-Lithiation
摘要:
Treatment of PhCO(2)H in tetrahydrofuran with 2.2 equiv of a 1:1 sec-butyllithium/N,N,N',N'-tetramethyl-1,2-ethylenediamine complex at -90 degrees C gave o-LiC6H4CO2Li, which was treated with electrophiles to give o-RC(6)H(4)CO(2)H (R = Me, SMe, Cl, Br) in good yields.
