چکیده
The title Schiff base compound, C(13)H(8)Cl(3)N(3)O(2), was synthesized by the condensation reaction of 3,5-dichloro-salicyl-aldehyde with 6-chloro-nicotinic acid hydrazide in 95% ethanol. The mol-ecule is nearly planar, with a dihedral angle of 1.9 (2)° between the aromatic ring planes, and an intra-molecular O-H⋯N hydrogen bond is observed. In the crystal, the mol-ecules are connected by inter-molecular N-H⋯O hydrogen bonds into infinite chains propagating in [100].

متن کاملMetabolism of dichloromethylcatechols as central intermediates in the degradation of dichlorotoluenes by Ralstonia sp. strain PS12.
Ralstonia sp. strain PS12 is able to use 2,4-, 2,5-, and 3,4-dichlorotoluene as growth substrates. Dichloromethylcatechols are central intermediates that are formed by TecA tetrachlorobenzene dioxygenase-mediated activation at two adjacent unsubstituted carbon atoms followed by TecB chlorobenzene dihydrodiol dehydrogenase-catalyzed rearomatization and then are channeled into a chlorocatechol or...
