Abstract

Under the optimized conditions, we investigated the I 2 -catalyzed reactions of various benzylic alcohols and benzylic acetates with acetylacetone. Both electron-rich and moderately electron-poor aromatic substrates reacted smoothly with acetylacetone and the corresponding benzylation products were isolated in excellent yields (Table [²] , entries 1-7). But when the reaction was carried out with the highly electron-deficient benzylic alcohol 1j, only trace amount of ...
