چکیده
The title compound, C(7)H(4)ClFO(2), is a twofold halogenated derivative of benzoic acid. The C-C-C angles within the aromatic moiety cover a range 116.11 (14)-123.96 (15)°, with the maximum and the minimum value next to each other. In the crystal, O-H⋯O hydrogen bonds form carb-oxy-lic acid dimers, which are further connected by C-H⋯F contacts into undulating sheets perpendicular to the a axis.

In the title compound, C7H6FNO2, the mol-ecule is almost planar (r.m.s. deviation for the non-H atoms = 0.015 Å) and an intra-molecular N-H⋯O hydrogen bond closes an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R2(2)(8) loops. Weak N-H⋯F hydrogen bonds, short F⋯F contacts [2.763 (2) Å] and aromatic π-π stacking inter-actions [centroid-centroid sep...

In the title Cu(II) complex, [Cu(C(7)H(4)FO(2))(2)(C(7)H(5)FO(2))(C(6)H(6)N(2)O)(2)], the Cu(II) cation is coordinated by two N atoms of two nicotinamide (NA) ligands, and by four O atoms from two 4-fluoro-benzoate (PFB) anions and one 4-fluoro-benzoic acid (PFBA) mol-ecule, in a distorted octa-hedral geometry. In the mol-ecule, two Cu-O bond lengths are significantly longer than the other two....

Reaction of thionyl chloride with 7-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4- oxoquinoline-3-carboxylic acid 1 gave acid chloride 2. Compound 2 was reacted with glycine and D-glutamic acid to afford 2-(7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4- dihydroquinoline-3-carbonyl) aminopantandioicacid 3a and 2-(7-chloro-1-cyclopropyl-6- fluoro -4- oxo-1,4-dihydroquinoline-3-carbonyl)aminoacetica...
متن کاملReductive dehalogenation of the trichloromethyl group of nitrapyrin by the ammonia-oxidizing bacterium Nitrosomonas europaea.
Suspensions of Nitrosomonas europaea catalyzed the reductive dehalogenation of the commercial nitrification inhibitor nitrapyrin (2-chloro-6-trichloromethylpyridine). The product of the reaction was identified as 2-chloro-6-dichloromethylpyridine by its mass fragmentation and nuclear magnetic resonance spectra. A small amount of 2-chloro-6-dichloromethylpyridine accumulated during the conversio...

The asymmetric unit of the title compound, [Zn(2)(C(7)H(4)FO(2))(4)(C(6)H(6)N(2)O)(2)]·C(7)H(5)FO(2), consists of a binuclear Zn(II) complex bridged by two carboxyl groups of 2-fluoro-benzoate (FB) anions and a 2-fluoro-benzoic acid mol-ecule. The two bridging FB anions, one chelating FB anion and one nicotinamide (NA) ligand coordinate to one Zn cation with a distorted square-pyramidal geometr...
