  摘要：

  Four heterocyclic salts 1a-d were prepared by Ca2+-assisted cyclization of fluoro derivatives 3, and investigated by spectroscopic (NMR and UV), electrochemical, and computational (DFT and MP2) methods. The mechanism for the formation of the cations was investigated at the DFT level of theory. 2-D NMR spectroscopy for 1[ClO4] in DMSO-d(6) aided with DFT results permitted the assignment of H-1 and C-13 NMR signals in cations 1. The molecular and crystal structures for 1a[ClO4] [C13H10ClNO4 triclinic, P-1, a=9.6517(12) angstrom, 6=11.0470(13) angstrom, c=12.2373(15) angstrom, alpha=67.615(1)degrees, beta=78.845(2)degrees, gamma=87.559(2)degrees; V=1183.0(2) angstrom(3). Z=4] and 1d[ClO4] [C12H9ClN2O4 triclinic, P-1, alpha=5.9525(6) angstrom, b=8.3141(9) angstrom, c=12.2591 (13) angstrom, alpha=73.487(1)degrees, beta=83.814(1)degrees, gamma=83.456(1)degrees; V=576.07(10) angstrom(3), Z=2] were determined by X-ray crystallography and compared with results of DFT and MP2 calculations. Electrochemical analysis gave the reduction potential order (1b>1c similar to 1d>1a), which is consistent with computational results. (C) 2011 Elsevier Ltd. All rights reserved.
