  Perchloro-2-methylnaphthalene, a Novel Chlorocarbon with a Highly Strained Structure

  摘要：

  Perchloro-2-methylnaphthalene (1) is prepared in a two-step reaction: treatment of 2H-heptachloronaphthalene (3) with CCl3F in the presence of AlCl3 yields heptachloro-7-(trifluoromethyl)naphthalene (4), which in CS2 and with an excess of AlCl3 affords 1. The spectra and X-ray crystal structure of chlorocarbon 1 are reported, as well as that of the much less strained heptachloro-7-(dichloromethyl)naphthalene (10). The unusual UV spectrum, due to the distortion of the aromatic rings, is also discussed. The reduction of 1 with copper wire to give perchloro(2-naphthyl)methyl radical (11) has been studied by means of electron spin resonance. Steric inhibition to resonance of the free electron within the aromatic ring in 11 has been estimated by a semiempirical AM1 method.

  Application of thermal kinetics to small carbon ion clusters

  摘要：

  Kinetic energy release distributions (KERDS') were obtained experimentally for unimolecular decomposition of small carbon ion clusters C(n)+, n = 10-13 and 18, made by dissociative ionization from perchloro conjugated hydrocarbons. A model-free approach due to Klots, based on the application of thermal kinetics to small systems, allowed the extraction of binding energies for these clusters. The results were found to be in very good agreement with literature values for collisionally activated dissociation (CAD) threshold energies. The ion C-11+ demonstrates a particularly high binding energy in agreement with its magic character in C(n)+ mass spectra, while C-13+ has a relatively low binding energy, reflected in its low abundance in such spectra.

  cluster ions (C(n).+, n = 10-18 and 20) in the gas phase with acrylonitrile (ACN) as the neutral reagent were investigated by Fourier transform ion cyclotron resonance spectrometry (FT-ICR). The carbon cluster ions studied were generated by electron impact ionization of perchlorinated polyaromatic compounds (PPA) and subsequent exhaustive chlorine elimination in the external ion source of the FT-ICR spectrometer
