1. A single oral dose of either [(14)C]Prefix or 2,6-dichlorobenzo[(14)C]nitrile to rats is almost entirely eliminated in 4 days: 84.8-100.5% of (14)C from [(14)C]Prefix is excreted, 67.3-79.7% in the urine, and 85.8-97.2% of (14)C from 2,6-dichlorobenzo-[(14)C]nitrile is excreted, 72.3-80.7% in the urine. Only 0.37+/-0.03% of the dose of [(14)C]Prefix and 0.25+/-0.03% of the dose of 2,6-dichlo...

In the title compound, [AuFe(C(5)H(5))(C(5)H(5)O(2)PS)(C(18)H(15)P)]·CH(2)Cl(2), the two-coordinate gold(I) atom shows a slightly distorted linear arrangement, with a P-Au-S bond angle of 176.81 (6)°. The difference in P=O and P-O(H) bond lengths, which are 1.503 (6) and 1.541 (5) Å, respectively, implies there is apparently no delocalization between the P-O bonds, and the proton appears to be ...

This paper describes the applicability of 1,3-dichloro-5,5-dimethylhydantoin, as a cheap, stable and commercially available catalyst, in the promotion of the synthesis of 1,8-dioxo-octahydro-xanthenes (DOXOs) via the one-pot condensation of aldehydes and cyclic 1,3-dicarbonyl compounds. This novel synthetic method has the advantages of high yields, short reaction times, low cost and av...

The structure of the title compound (26DCP4MeBA), C(14)H(10)Cl(2)O(2), resembles those of phenyl benzoate (PBA), 2,6-dichloro-phenyl benzoate (26DCPBA), 2,4-dichloro-phenyl 4-methyl-benzoate (24DCP4MeBA) and other aryl benzoates, with similar bond parameters. The dihedral angle between the benzene and benzoyl rings in 26DCP4MeBA is 77.97 (9)°, compared with values of 55.7 (PBA), 75.75 (10) (26D...

The structure of the title compound, C(14)H(13)NO, resembles those of N-(2-chloro-phen-yl)benzamide, 2-chloro-N-phenyl-benzamide, N-(2,3-dichloro-phen-yl)benzamide, N-(3,4-dichloro-phen-yl)benzamide and 2-chloro-N-(2-chloro-phen-yl)benzamide with similar bond parameters. The benzene and methylphenyl rings have a dihedral angle of 63.41 (5)°, while the amide group makes a dihedral angle of 20.5 ...

In the mol-ecule of the title compound, C(20)H(16)Cl(2)N(2)O(2), the planar benzimidazole ring system is oriented with respect to the furan and dichloro-benzene rings at dihedral angles of 53.39 (6) and 31.04 (5)°, respectively. In the crystal structure, inter-molecular C-H⋯Cl hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(8) dimers. These dimers are connected via a C-H⋯π cont...

In the title compound, C(25)H(13)Cl(2)F(4)N(3), there are four planar systems, viz. three benzene rings and a pyrazolo-[1,5-a]pyrim-idine system [r.m.s. deviation = 0.002 Å]. The dihedral angle between the dichloro-phenyl ring and the unsubstituted phenyl ring is 69.95 (5)°, while that between the fluoro-phenyl ring and the unsubstituted phenyl ring is 7.97 (10)°. The crystal packing is dominat...

In the title compound, C(25)H(21)N(5)O(3)S·CH(2)Cl(2), the dichloro-methane solvent mol-ecule is disordered over four positions, with an occupancy ratio of 0.271 (3):0.3884 (18):0.298 (2):0.0424 (15). The 1,2,4-triazole ring makes dihedral angles of 47.3 (2)/87.3 (2) and 3.6 (2)° with the phenyl and nitro-phenyl rings, respectively. An intra-molecular C-H⋯S hydrogen bond results in the formatio...
