When iodides are administered in ordinary doses excretion takes place rapidly. Heavy doses can usually be administered before toxic symptoms develop. The same is true to an even greater extent of bromides. The bromide ion appears to be capable of replacing the chloride ion to a Considerable degree in the body fluid of mammals without the production of distinct toxic symptoms. Thus Frey (1910--1...

Hexamethylene-1,6-bis-(N,N-dimethyl-N-dodecylammonium bromide), pentamethylene-1,5-bis(N,N-dimethyl-N-dodecylammonium bromide), tetramethylene-1,4-bis(N,N-dimethyl-N-dodecylammonium bromide), trimethylene-1,3-bis(N,N-dimethyl-N-dodecylammonium bromide) and ethylene-1,2-bis(N,N-dimethyl-N-dodecylammonium bromide) have been obtained and characterized by FTIR and NMR spectroscopy. DFT calculations...

The metabolism of halothane during and after anaesthesia was studied in eight patients of different age and body weight by estimating the concentration of halothane and one of its metabolites (bromide) in the blood. A gas chromatograph with an electron capture detector was used to estimate halothane, while blood bromide levels were measured by neutron activation analysis. There was an initial b...

2- Ethoxy-4(3H) quinazolinone 1 was synthesized and allowed to react with various halides, namely: alkyl, benzyl, allyl, acyl, haloacetyl, crotonyl, benzoyl, 2-furoyl and 1-naphthalenesulphonyl halides affording quinazoline and quinazolinone derivatives. The reactions of compound 1 with phosphorus oxychloride, phosphorus pentasulfide, ethyl chloroformate, ethyl chloroacetate, ?-bromoglucose tet...

In the title compound, C(19)H(14)ClNO(5), the aroyl group is attached to the naphthalene ring system with a non-coplanar configuration. The dihedral angle between naphthalene ring system and benzene ring is 70.62 (6)°. The nitro group is oriented in parallel with the adjacent carbonyl plane. The torsion angle of the carbonyl group and naphthalene ring is 54.68 (19)° (C-C-C-O), and that of nitro...

A simple route to 3-oxoalkanonitrile 5, aprecursor of the title compounds is described. Reaction of enaminones 2 with hydroxylamine hydrochloride in ethanol yielded aldoximes 3 that were converted readily into 5 in basic medium. This method has been successfully applied with a number of substrates and resulted in excellent yields of the products. Reacting 5 with trichloroacetonitrile afforded 3...
