2,2-Dibromo-3-Nitrilopropionamide, a Compound with Slimicidal Activity

1,2-Dibromo-3-chloropropane.

2,3-Dibromo-3-phenyl­propionic acid

In the crystal of the title compound, C(9)H(8)Br(2)O(2), inversion dimers linked by two O-H⋯O hydrogen bonds occur. All of the carbon and oxygen atoms are disordered over two sets of sites in a 2:1 ratio.

2,4-Dibromo-6-[(E)-({3-[(E)-(3,5-dibromo-2-oxidobenzyl­idene)aza­nium­yl]-2,2-dimethyl­prop­yl}iminium­yl)meth­yl]phenolate

In the title mol-ecule, C(19)H(18)Br(4)N(2)O(2), the dihedral angle between the benzene rings is 73.9 (2)°. Two intra-molecular N-H⋯O hydrogen bonds make S(6) ring motifs. In the crystal, mol-ecules are linked via C-H⋯O inter-actions, forming chains propagating along the a-axis directon. A short C⋯Br [3.401 (5) Å] contact is present in the crystal structure, which is further stabilized by a π-π...

Movement and Persistence of 1,2-dibromo-3-chloropropane in a Soil with a Plow-pan.

Movement and persistence of 1,2-dibrotno-3-chloropropane (DBCP) in a Coastal Plain soil containing a sandy plow-pan were enhanced in each of 2 years by subsoiling, increased depth of application, and increased rate of application. DBCP was extracted from the soil with hexane and analyzed by gas chromatography. Subsoiling at a 35-cm depth gave the greatest increase in lateral movement and downwa...

Anticonvulsant Activity of Schiff Bases of 3-Amino-6,8-dibromo-2-phenyl-quinazolin-4(3H)-ones

Schiff bases (9a-l) of 3-amino-6,8-dibromo-2-phenyl-quinazolin-4-(3H)-ones (8) with various substituted aldehydes were obtained by refluxing 1:1 molar equivalents of the reactants in dry ethanol for 6 h. The aminoquinazoline (8) was inturn obtained from 3,5-dibromoantharlinic acid via intermediate (7). All the synthesized compounds (9a-l) were evaluated for their anticonvulsant activity on albi...
