N 4,N 6-Dimethyl-5-nitro-N 4,N 6-diphenylpyrimidine-4,6-diamine
In the title compound, C(18)H(17)N(5)O(2), the pyrimidine ring makes dihedral angles of 66.09 (12), 71.39 (13) and 56.7 (3)° with two phenyl rings and the nitro group, respectively. The dihedral angle between the two phenyl rings is 44.05 (14)°.
متن کامل4-Bromo-N 2,N 2,N 6,N 6-tetraethylpyridine-2,6-dicarboxamide
The title compound, C(15)H(22)BrN(3)O(2), consists of a pyridine ring with a bromine atom in the para position and two diethyl-amide groups in the ortho positions of the ring. Despite the positions of the three substituents on the pyridine ring, the mol-ecule does not exhibit either local or crystallographic twofold symmetry as the two diethyl-amido units exhibit significantly different N(py)-C...
متن کاملN 4,N 6-Dimethyl-N 4,N 6-diphenylpyrimidine-4,5,6-triamine
In the title compound, C(18)H(19)N(5), the pyrimidine ring makes dihedral angles of 56.49 (9) and 70.88 (9)° with the phenyl rings. The dihedral angle between the two phenyl rings is 72.45 (9)°. No significant inter-molecular inter-actions are observed in the crystal structure.
متن کاملN 2,N 2,N 6,N 6-Tetrakis(2,3,4,5,6-pentafluorobenzoyl)pyridine-2,6-diamine
The title compound, C(33)H(3)F(20)N(3)O(4), is a highly fluorinated organic imide that was isolated as an unexpected product from the reaction of 2,6-diamino-pyridine with 2,3,4,5,6-penta-fluoro-benzoyl chloride in a 1:2 molar ratio. The mol-ecule is located on a twofold axis and one of its symmetry-independent 2,3,4,5,6-penta-fluoro-benzoyl groups is disordered over two sets of sites, the occu...
متن کاملC−H Cyanation of 6‐Ring N‐Containing Heteroaromatics
Heteroaromatic nitriles are important compounds in drug discovery, both for their prevalence in the clinic and due to the diverse range of transformations they can undergo. As such, efficient and reliable methods to access them have the potential for far-reaching impact across synthetic chemistry and the biomedical sciences. Herein, we report an approach to heteroaromatic C-H cyanation through ...
