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 ca

In the mass spectra of 2-stilbazoles 1a - 1g and 3- and 4-stilbazoles (2 resp. 3), C13H10N+ ions, m/z = 180, are formed with high intensities by loss of a H-atom or of a substituent.This is the only fragmentation reaction available to metastable molecular
