Abstract
1-[1-(Benzotriazol-1-yl)alkyl]-1
H-benzotriazoles undergo deprotonation with
n-BuLi at the α-position of the
N-substituent and at the 7-position of benzotriazole to afford polyanions. Treatment of these polyanions with electrophiles allows the preparation of highly functionalized benzotriazole derivatives.
