1-(4-Chlorophenyl)-3-(3-chloropropionyl)thiourea
In the title compound, C10H10Cl2N2OS, the mol-ecule adopts a trans-cis conformation with respect to the position of the carbonyl group and the chloro-phenyl groups relative to the thiono group across the C-N bonds. The mol-ecule is stabilized by an N-H⋯O hydrogen bond. In the crystal, mol-ecules are linked by N-H⋯S and C-H⋯O hydrogen bonds, forming zigzag chains along the b-axis direction. C-H⋯...
متن کامل1-(3-Chlorophenyl)-3-(1-p-tolylimidazolidin-2-ylidene)urea
In the crystal structure of the title compound, C(17)H(17)ClN(4)O, the existence of only one 2-imino-oxo of the five possible N-amino-imino/O-keto-hydr-oxy tautomers is observed and the dihedral angle between the aromatic rings is 29.78 (11)°. The mol-ecular conformation is stabilized by intra-molecular C-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds, in each case generating a six-membered ring. In the c...

The title chalcone (E)-1-(2-aminophenyl)-3-(4-chlorophenyl)prop-2-en-1-one was prepared with an excellent yield from a Claisen–Schmidt condensation reaction between o-aminoacetophenone and p-chlorobenzaldehyde. This product will be used as a key precursor for the development of an alternative route for the total synthesis of dubamine and graveoline alkaloids. Single crystals of the title compou...
متن کاملAbsorption of 2,4-Dichlorophenoxyacetic Acid and 3-(p-Chlorophenyl)-1, 1-dimethylurea (Monuron) by Barley Roots.
Absorption from culture solution of the herbicides 2, 4-dichlorophenoxyacetic acid (2, 4-D) and 3-(p-chlorophenyl)-1, 1-dimethylurea (Monuron) by excised barley (Hordeum vulgare L.) roots was studied to determine whether absorption was due to an active or a passive mechanism. Herbicide absorption was followed at low temperature, under anaerobic conditions, and in the presence of metabolic inhib...
متن کاملAb Initio Study of Conformational and Configurational Properties of 1, 3- Diazacyclohepta-1, 2-diene and 1, 3-Diazacycloocta-1, 2-diene
Ab initio calculations at HF/6-31G* level of theory for geometry optimization and MP2/6-31G*//HF/6-31G* for a single point total energy calculation are reported for the importantenergy-minimum conformations and transition-state geometries of 1, 3-diazacyclohepta-1, 2-diene (2) and 1, 3-diazacycloocta-1, 2-diene (3). The C2 symmetric twist-chair (2-TC)conformation of 2 is calculated to be 7.4 kJ...
