Generation and reactivity of polyanions derived from 1-[1-(benzotriazol-1-yl)alkyl]-1H-benzotriazoles
摘要:
1[1(Benzotriazol-1yI)alkyl]-1H-benzotriazoles undergo deprotonation with n-BuLi at the alpha-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. (c) 2005 Elsevier Ltd. All rights reserved.
