Abstract
Reactions of α-silicon-and α-germanium-containing acetylenic aldehydes with 2-aminoethanethiol, ethylenediamine, and 2-amino-1,2,4-triazole proceed chemoselectively at the aldehyde group. The ratio of tautomers, azomethine and 1,3-thiazolidine, on interaction with 2-aminoethanethiol depends significantly on the nature of the heteroatom at the triple bond of the aldehyde, the presence of a catalyst, and the use of microwave activation.
