Abstract
Using quantum chemical and kinetic techniques, we show that the reaction between two HCN molecules under interstellar conditions cannot lead efficiently to a dimer of this species (H2C2N2), whatever its structure. If the dimerization reaction does not occur efficiently, then it is impossible to synthesize detectable abundances of the pre-biotic HCN oligomer adenine (H5C5N5) in the interstellar medium via successive neutral-neutral reactions between HCN and its dimer, trimer, and tetramer.
