The solvated title compound, bis-[2,6-bis-(1-{[4-(di-methyl-amino)-phen-yl]imino-κN}eth-yl)pyridine-κN]nickel(II) dichloride-di-chloro-methane-water (1/2/2), [Ni(C25H29N5)2]Cl2·2CH2Cl2·2H2O, represents a nickel(II) bis-(pyridine di-imine) complex with electron-donating di-methyl-amino-phenyl substituents. The complex crystallizes as a water/di-chloro-methane solvate with Z' = 2, thus the asymme...

the effect of four inhibitors on calmalulin (cum) were studied by a ftuorescence and ultraviolet techniques. four compounds in - ( 6 - aminohexyt) 5-chloro - i - napthalenesulphonamide] (w-7), 1 - [ bis - (4 - chtorophenyt) methyl] - 3 - [2, 4-dichloro - β - ( 2 , 4 - dichlorobenzyloxyl) phenethyt] imidazolium chloride (r24571), trifluoperazine (tfp) , thiodiphenylamide chloride (tdpac) showed ...

A series of methyl 6-Chloro-2-Substitued-1-[2-(1H-tetrazol-5-yl)-biphenyl-4-ylmethyl]1H-benzoimidazol-5-ylamine were successfully synthesized. Benzimidazoles were prepared by condensation of 4-chloro-o-phenylenediamine with substituted aryl, aldehyde condensation with biphenyl tetrazole group and reduction stannous chloride dihydrate. An insertion-cyclization strategy was involved during synthe...

The title compound, C(19)H(14)ClFN(2)O(3), was prepared by the reaction of ethyl (Z)-3-amino-2-cyano-3-(4-fluoro-phen-yl)acrylate and 4-chloro-benzoyl chloride. The dihedral angle between the chloro-benzene and fluoro-benzene rings is 66.18 (19)°. In addition to an intra-molecular N-H⋯O hydrogen bond, there are inter-molecular C-H⋯O and C-H⋯N hydrogen bonding inter-actions, which stabilize the ...

The title compound, C(19)H(14)ClO(2)PSe, was obtained in the reaction of the diphenyl-monoseleno-phosphinic acid ammonium salt with 4-chloro-benzoyl chloride. The dihedral angle between the P-bonded aromatic rings is 72.64 (14)°. Packing of the mol-ecules in the crystal is reinforced by π-π stacking inter-actions between two inversion-related 4-chloro-benzene rings [centroid-centroid separation...

The title compound, C(12)H(8)Cl(2)N(4)O, was synthesized by the reaction of 5-amino-1-(4-chloro-phen-yl)-1H-pyrazole-3-carbonitrile and 2-chloro-acetyl chloride. The dihedral angle between the pyrazole and benzene rings is 30.7 (3)°. In the crystal structure, strong N-H⋯O hydrogen bonds link the mol-ecules into chains along [001]. C-H⋯N hydrogen bonds are also present.

Deacetoxylation of the oxo-centered triruthenium acetate cluster by acetyl chloride or triethylsilyl chloride led to the formation of a versatile precursor [Ru(3)O(OAc)(5)(Cl)(4-methylpyridine)(2)(CNt-Bu)], whose chloro ligand was readily substituted by other bridging ligands, i.e. alkoxides, carboxylates or sulfides.

A microorganism capable of degrading 4-chloro-2-methylphenoxyacetic acid (MCPA) was isolated from soil and identified as Flavobacterium peregrinum. All of the chlorine of MCPA was released as chloride, and the carboxyl-carbon was converted to volatile products by growing cultures of the bacterium, but a phenol accumulated in the medium. The phenol was identified as 4-chloro-2-methylphenol on th...
