AUTOCOMPLEXES OF THE PICRYL SERIES WITH A ONE-MEMBERED O-BRIDGE
A series of new autocomplexes of the picryl series with a one-membered bridge were synthesized from picryl chloride and a series of substituted phenols.The relationships governing intramolecular charge transfer in the synthesized compounds were studied by
SPIROCYCLIC MEISEHEIMER COMPLEXES XXVI. STRUCTURE AND TAUTOMERISM OF PICRYL DERIVATIVES OF 2-PYRIDINEMETHANOL AND 8-QUINOLINOL
By means of x-ray structure analysis and IR spectroscopy it was shown that the picryl derivative of 2-pyridinemethanol in the crystalline state exists as a zwitterion spirocyclic complex of the Meisenheimer type, which in solution is in equilibrium with the open form: 2-pyridine.The state of equilibrium in various solvents is described by the Pal'm-Koppel' equation.In contrast to this, 8-(picryloxy)quinoline exists as the open ether form both in solution and in the crystalline state.
