Methyl 3-[3-(ethoxycarbonyl)thioureido]-1H-pyrazole-5-carboxylate
The title compound, C(9)H(12)N(4)O(4)S, was proven to be the product of the reaction of methyl 5-amino-1H-pyrazole-3-carboxyl-ate with ethyl isothio-cyanato-carbonate. All non-H atoms of the mol-ecule are planar, the mean deviation from the least squares plane being 0.048 Å. The intra-molecular N-H⋯O bond involving the NH-group, which links the thio-urea and pyrazole fragments, closes a six-mem...
متن کاملCrystal structure of 3-methyl-5-trimethylsilyl-1H-pyrazole
The title compound, C7H14N2Si, crystallizes in a tetra-gonal space group and exists as an N-H⋯N hydrogen-bonded tetra-mer, formed around the crystallographic fourfold rotoinversion axis. The mol-ecular identity is clearly the 5-tri-methyl-silyl-3-methyl-1H-pyrazole tautomer and the structure is isomorphous with that of 5-tert-butyl-3-methyl-1H-pyrazole [Foces-Foces & Trofimenko (2001 ▶). Acta C...
متن کاملAcetylation of methyl 5-amino-1H-[1,2,4]triazole-3-carboxylate.
Acetylation with acetic anhydride of methyl 5-amino-1H-[1,2,4]triazole-3-carboxylate, one of the hetareneamino acids, was studied using HPLC, H NMR, FTIR and GC-MS. The compound has a significantly decreased susceptibility to acetylation compared to 5-amino-1H-[1,2,4]triazole itself. Two isomeric diacetylated products were found.
متن کامل3-Methyl-5-phenoxy-1-phenyl-1H-pyrazole-4-carbaldehyde
In the title compound, C(17)H(14)N(2)O(2), the pyrazole ring makes dihedral angles of 73.67 (4) and 45.99 (4)°, respectively, with the adjacent phenyl and phen-oxy rings. In the crystal, there are no classical hydrogen bonds, but a weak C-H⋯π inter-action is observed.
متن کامل1-(2,4-Dinitrophenyl)-5-ferrocenyl-3-methyl-1H-pyrazole
In the title compound, [Fe(C(5)H(5))(C(15)H(11)N(4)O(4))], the dinitro-phenyl and cyclo-penta-dienyl rings make dihedral angles of 53.61 (6) and 23.11 (9)°, respectively, with the pyrazole unit. The two cyclo-penta-dienyl rings are in an eclipsed conformation. The crystal structure is stabilized by inter-molecular C-H⋯O inter-actions, which link mol-ecules into chains parallel to the b axis.
