## Abstract The addition of electrophilic reagents to ethyl (ethylthio)propynoate II occurs at carbon atom 2. Uncharged nucleophilic reagents (amines) are also added at carbon atom 2, but charged nucleophiles (ethoxide ion and the carbanion of malonic ester) interact at carbon atom 3. Additions to
A new cocrystalline salt, 5-bromo-2-aminopyridinium propynoate 7, has been synthesized. Inspection of the crystal structure reveals that the packing differs markedly from that of the chemically analogous species 2-aminopyridinium propynoate 1. While 1 undergoes a thermally-induced Michael addition r
Sodium propynoate, Na(O 2 CC,CH) 1, was synthesized from propynoic acid and sodium hydroxide in methanol solution. Irradiation of solid 1 with 60 Co -rays (654 kGy dose) leads to an amorphous dark-colored acetylenic polymer in high yield. An X-ray structure determination of compound 1 shows that the
