Thermochemical and kinetic aspects of metal picrates [PDF]
, 1983 The standard enthalpies of formation of ammonium picrate, picric acid, 2,4-dinitrophenol, 2,6-dinitrophenol and methylurea have been determined by oxygen static bomb calorimetry as [diagrams] From solution calorimetry, standard enthalpies of formation ...

The synthesis of 4H-pyran containing hemispherands via pyrylium salts [PDF]
, 1986 Two new hemispherands 2a and 2b containing a central 4H-pyran unit were synthesized via appropiately substituted 2,6-phenyl pyrylium salts; largest ΔGo values of complexation of 2a and 2b with different alkali picrates are found for Na+ and K+
