1,3,5-Triazines substituted with mono-, di, and tri-[4-(2-chloroethyl)piperazin-l-yl] groups gave products of substitution of chlorine atom when treated with ethanol, phenol, butylamine, toluidine,or thiophenol under mild reaction conditions.
interest in agrochemicals and drugs. Aryl group substituted pyrazoles and imidazoles, in particular, have been studied because their biological activities are strongly dependent on their substituents on the pyrazole ring system. 1,5-Diaryl substituted pyrazole (SR141716A, 1), which has a hydrazide group on the 3-position of the pyrazole ring, has recently been synthesized and identified as the ...
The title mol-ecular salt, C5H12NO(+)·C12H8N5O9 (-) [common name: 4-methyl-morpholin-4-ium 1,3-dimethyl-5-(2,4,6-tri-nitro-phen-yl)barbiturate], possesses noticeable anti-convulsant and hypnotic activity. In the anion, the 1,3-di-methyl-barbituric acid ring and the symmetrically substituted tri-nitro-phenyl ring, linked via a C-C bond, are not coplanar but subtend an angle of 44.88 (7)°. The si...
