N 1,N 4-Diethynyl-N 1,N 4-diphenylbenzene-1,4-diamine
The title compound, C(22)H(16)N(2), is the first example of an ynamine with H atoms bonded to the terminal C atoms. The environment around each N atom is almost planar. The distances of the N atoms from a least squares plane fitted through each N atom and the surrounding three C atoms, are 0.087 (3) and 0.041 (4) Å. The dihedral angles between these two planes and the central phenyl-ene ring ar...
متن کاملThe (14)N quadrupole coupling in hexamethylene triperoxide diamine (HMTD).
Using high-field NMR, we have determined the magnitude of the nuclear quadrupole interaction in hexamethylene triperoxide diamine (HMTD), the explosive allegedly used in the London bombings of July 2005. The experimental quadrupolar coupling constant, 5.334 MHz, is in good agreement with quantum chemical calculations. The predicted single zero-field transition frequency should lie in a relative...
متن کاملRole of unsaturated derivatives of spermidine as substrates for spermine synthase and in supporting growth of SV-3T3 cells.
Synthetic unsaturated analogues of the natural polyamine were examined as possible substrates for spermine synthase and as replacements for spermidine in supporting the growth of SV-3T3 cells. It was found that N-(3-aminopropyl)-1,4-diamino-cis-but-2-ene [the cis isomer of the alkene analogue of spermidine] was a good substrate for spermine synthase, but that the trans isomer [N-(3-aminopropyl)...
متن کامل3-Methylbenzene-1,2-diamine
The title compound, C7H10N2, was synthesized from 2-methyl-6-nitro-aniline by a reduction reaction. In the crystal, molecules are linked via N-H⋯N hydrogen bonds, forming two-dimensional networks lying parallel to (100). These networks are stabilized by C-H⋯π and N-H⋯π inter-actions.
متن کاملPyridine-2,3-diamine
The mol-ecule of the title pyridine derivative, C(5)H(7)N(3), shows approximately non-crystallographic C(s) symmetry. Intra-cyclic angles cover the range 117.50 (14)-123.03 (15)°. In the crystal, N-H⋯N hydrogen bonds connect mol-ecules into a three-dimensional network. The closest inter-centroid distance between two π-systems occurs with the c-axis repeat at 3.9064 (12) Å.
