Fragmentation of α-Acetoximino Ketoesters in Polyphosphoric Acid |
|
| Authors: | Sheng-Hsu Zee Shan-Yen Chou |
| Abstract: | Fragmentations of various α-acetoximino ketoesters in neat polyphosphoric acid medium to form acylium ions were studied. The resulting acylium ions were trapped by benzene rings either intermolecularly or intramolecularly. |
