| Abstract: | 3-Trimethylsilylprop-2-ynal reacted with aliphatic α-hydroxyamino oximes in a chemoselective fashion at the aldehyde group to give hitherto unknown open-chain 3-trimethylsilylprop-2-yn-1-ylideneamine oxides. The possibility for intramolecular hydrogen bonding with participation of OH, C≡C, and N→O groups in the products was studied by IR spectroscopy. |
