چکیده
In the title compound, C(6)H(4)ClF(3)N(2), an inter-mediate in the synthesis of the fungicide fluazinam, the F atoms of the trifluoro-methyl group are disordered over two sites in a 0.683 (14):0.317 (14) ratio. In the crystal structure, centrosymmetric dimers arise from pairs of N-H⋯N hydrogen bonds.

In the title compound, C(5)H(5)ClN(2), a by-product in the synthesis of ethyl 2-(3-chloro-pyridin-2-yl)-5-oxopyrazolidine-3-carboxyl-ate, the amine groups form inter-molecular hydrogen-bonding associations with pyridine N-atom acceptors, giving centrosymmetric cyclic dimers. Short inter-molecular Cl⋯Cl inter-actions [3.278 (3) Å] also occur.
متن کاملThe conversion of [(4-chloro-5H-1,2,3-dithiazol-5-ylidene)amino]azines into azine fused thiazole-2-carbonitriles.
The thermolysis of several N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)pyridin-n-amines (where n = 2, 3 and 4) gives a mixture of thiazolopyridine-2-carbonitriles in low to moderate yields. Introduction, by design, of a chlorine substituent at the C2 or C4 position of N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)pyridin-3-amine and other selected azines enables a BnEt(3)NI mediated ANRORC style ring t...

In the title compound, [CuCl(C17H19Cl4N3)]ClO4, the Cu(II) ion adopts a distorted square-planar geometry defined by one chloride ligand and the three nitro-gen atoms from the bis-[(pyridin-2-yl)meth-yl](3,5,5,5-tetra-chloro-pent-yl)amine ligand. The perchlorate counter-ion is disordered over three sets of sites with refined occupancies 0.0634 (17), 0.221 (16) and 0.145 (7). In addition, the het...
