Ethynol (“hydroxyacetylene”) 2 has been considered as a possible constituent of interstellar clouds, planetary atmospheres, and flames. Compound 2 was generated photochemically from 1 and investigated both spectroscopically and kinetically. The observed photoisomerization to the more stable tautomeric ketene 3 , however, is evidence against an appreciable presence of 2 in interstellar space.
