Unusual KF/Al2O3 promoted tandem electrophilic-nucleophilic aromatic substitution leading to the xanthone formation
摘要:
Formation of xanthone (III) by the KF/Al2O3 mediated O-alkylation of 2-hydroxybenzophenone (I) is described and mechanistic rationalization is proposed for this unexpected side-reaction.
