Cyanoacetylenes as precursors for reactive and interstellar intermediates

As described already some time ago [54], 70-eV electron impact ionization of 2 [Eq. (16)] and 3 [Eq. (17)] affords by direct cleavage processes the complete series of C N ions. 

As these few examples demonstrate, cyanoacetylenes are indeed useful and versatile precursor molecules for the generation of highly reactive molecules and clusters, and it can safely by assumed that novel insights into the mechanisms of formation of these species and their electronic structures will come forth, with more - and structurally new — cyanocarbons becoming available.
