Abstract
Photoelectron spectra of R2NC$\equiv$CNR2 and of (R2N)2C:C:C(NR2)2 (I; R = Me, Et) exhibit halves twisted against each other. The low 1st ionization potentials at 7.0-7.7 eV stimulated attempts to oxidize using AlCl3 in CH2Cl2 or CD2Cl2. The hyperfine-structured ESR spectra obsd. can be assigned unequivocally to the ethylene radical cations R2NHC:CHNR2.bul.+, which are formed from the obviously nonpersistent species R2NC$\equiv$CNR2.bul.+ via H transfer. No paramagnetic intermediates were detected during I oxidn., presumably owing to rapid dimerization of (R2N)2C:C:C(NR2)2.bul.+. on SciFinder(R)
