The reaction of 4,5-dichloro-1,2,3-dithiazolium chloride with 2-(phenylsulfonyl)acetonitrile (1 equiv) in the presence pyridine (2 gave S-(3-chloro-5-cyanoisothiazol-4-yl)benzenesulfonothioate and (Z)-2-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-2-(phenylsulfonyl)acetonitrile 19% 23% yield, respectively. compounds were fully characterized mechanistic rationale is proposed for formation benzensulfo...

A rat liver mitochondrial-matrix fraction was prepared and shown to have 1-chloro-2,4-dinitrobenzene(CDNB)-metabolizing glutathione transferase (GST) activity. Further fractionation by sequential gel filtration, isoelectric focusing or chromatofocusing and hydroxyapatite chromatography yielded three GSTs of pI 9.3, 8.9 and 7.5, none of which bound to a GSH-agarose affinity matrix. Most of the a...

There are two mol-ecules in the asymmetric unit (Z' = 2) of the title compound, C(13)H(14)ClN(3), Each mol-ecule is linked by N-H⋯N hydrogen bonds to another of the same type in a chain in [110]. The crystal studied was a non-merohedral twin with components 0.622 (2) and 0.378 (2).

In the crystal structure of the title compound, C(9)H(6)Cl(3)NO(3), mol-ecules are connected by C-H⋯O hydrogen bonds, forming chains along the b axis. The dihedral angle between the benzene ring and the plane of the nitro group is 16.2 (1)° and that between the benzene ring and the plane of the dichloro-allyl group is 10.2 (1)°.
