gem-DIALKOXYLATION OF 2-ACETYLTHIOPHENES AND 2-ACETYLFURANS

Article abstract of DOI:10.1007/BF00486908

Reaction of 2-acetyl-substituted thiophenes and furans with alkyl nitrites in the presence of the corresponding aliphatic alcohols and hydrochloric acid leads to the formation of linear acetals of thienyl- and furylglyoxals, whose structure was established by IR, UV, NMR spectroscopy, and mass spectrometry methods.The main paths of the dissociation of the molecules under electron impact were established.
