چکیده
The mol-ecule of the title compound, C(5)H(4)Cl(2)N(2)O, is close to being planar (r.m.s. deviation = 0.013 Å), apart from the C atom of the meth-oxy group, which deviates by 1.082 (2) Å from the mean plane of the other atoms. In the crystal, short Cl⋯N contacts [3.0940 (15) and 3.1006 (17) Å] generate a three-dimensional framework.

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...
