The molecular and crystalline structures of three products of the reaction between 2,7-dinitro- and 2,4,7-trinitrophenanthrenequinone with nitromethane in an HMPTA solution were studied by x-ray diffraction. Two of these products are H-bonded 1:1 solvates.A. N. Nesmeyanov Institute of Heteroorganic Compounds, Russian Academy of Sciences, 117813 Moscow.

Phenanthrenequinone monoxime and its mono-, di-, and trinitro derivatives were synthesized. The acidity constants and their
variation with the number and position of nitro groups were determined. The electronic and IR spectra of the nitro compounds
were studied. The bands in the electronic spectra were assigned based on quantum-chemical calculations in the Pariser—Parr—Pople
approximation. Correlations between the pK
a values and some calculated characteristics of the compounds under study were found.

The addition of acetone to 9,10-phenanthrenequinone and 2-nitro-, 2,7-dinitro-, and 2,4,7-trinitro-9,10-phenanthrenequinones in the presence of Al2O3 affords mono- and bisadducts. The crystal structures of 10-hydroxy-10-(2-oxopropyl)-2-nitro-9,10-dihydrophenanthren-9-one and 9,10:10,9-bishemiketal of 9,10-dihydroxy-2-nitro-9,10-bis(2-oxopropyl)-9,10-dihydrophenanthrene were determined. 相似文献
