Abstract

More than 20% of all identified organic molecules in interstellar space contain either an amino moiety or a CC triple bond. The simplest molecule which contains both these structural units is aminoacetylene (ethynamine). It follows from ab initio calculations of the C//2H//3N hypersurface that aminoacetylene (ethynamine) which so far has not been generated and characterized, should be a stable species, at least in the gas phase. The authors have succeeded in generating aminoacetylene and its mono- and dications. It is concluded that neutralization of 1a produces the long sought aminoacetylene; isomerization to thermodynamically more stable C//2H//3N species does not occur. It should also be mentioned that under the conditions of charge stripping, aminoacetylene (ethynamine) can be oxidized to a C//2H//3N dication.
