A method is developed for the preparation of 4-(vic-triazol-1-yl)indoles that involves replacement of the ortho-NO2 group in E-2,4,6-trinitrostilbenes by an azido group, condensation of E-2-azido-4,6-dinitrostilbenes with acetylacetone, replacement o

Conditions were found under which 2,4,6-trinitrostyrene derived from 2,4,6-trinitrotoluene adds nucleophiles (thiophenol, aniline, and aliphatic amines) at the vinyl fragment to form the corresponding β-X-ethyl-2,4,6- trinitrobenzenes (X = PhS, PhNH

The interaction of the demethylation product of 1, 3, 5-trinitrobenzene—2, 4, 6-trinitrotoluene—with fluorinated alcohols followed by reduction of the perfluoroalkoxy-substituted m-dinitrobenzenes thus formed led to the formation of new fluorinat
