Anionic polymerization of an acrylonitrile trimer studied by photoelectron spectroscopy
A photoelectron spectrum of an acrylonitrile (A-NL:CH2=CHCN) trimer anion, (AN)(3)(-), produced by electron impact on an acrylonitrile cluster was measured, and was compared with that of a molecular anion of 1,3,5-cyclohexanetricarbonitrile (c-HTCN) in the triequatorial form, which was first synthesized in the present experiment. A comparison of the vertical detachment energies of (AN)(3)(-) and the molecular anion lead us to conclude that (AN)(3)(-) is assigned as one of the stereoisomers (diaxial form) of c-HTCN (-) on the basis of our previous studies refs 13, 14, and 20-22 [Tsukuda, T.; Kondow, T.
