Selective Oxidation of the 4-Ethyl-3-methylcinnoline Methylene Group by Al 2 O 3 -Supported Chromium Oxide
RUSSIAN JOURNAL OF GENERAL CHEMISTRY(2023)
摘要
The optimal conditions for the oxidation of the methylene group in 4-ethyl-3-methylcinnoline to the corresponding ketone, 3-methyl-4-acetylcinnoline, were selected. It was shown that preliminary deposition of 4-ethyl-3-methylcinnoline on some inorganic substrates has a significant effect both on the selectivity of the oxidation of only the methylene group and on a high degree of conversion to the target product.
