By using alkylbenzenes as aroyl surrogates, copper(II) catalyzed chemoselective O-aroylations of 1,3-dicarbonyl compounds and phenolic-OH ortho to carbonyl (-CHO,-COR) groups have been achieved. A dual mechanism operating in tandem for these transformations has been supported by a crossover experiment.
The Synthesis and Spectroscopic Properties of Flavones: Special Mass Spectral Characteristics of 3-Methylflavones
Letcher, Roy M.
, p. 2901 - 2929 (2007/10/02)
The synthesis of twenty one methyl-, methoxy-, nitro- and halogen-substituted 3-methylflavones is described, and their spectroscopic characteristics are reported.In contrast to the mass spectra of 3-unsubstituted flavones, the most abundant ion exhibited
