S-Benzylthiuronium Salts.

Utility of S-Benzylthiuronium Chloride in the Synthesis of Heterocyclic Systems

Abstract: 4-Amino-2-(benzylthio)-6-(4-chlorophenyl)pyrimidine-5-carbonitrile 1 was prepared by treatment of s-benzylthiuronium chloride with 2-(4-chlorobenzylidene) malononitrile in ethanolic sodium hydroxide and subjected to react with hydrazine hydrate to afford the hydrazino derivative 2 which was allowed to react with different electrophilic reagents to give the pyrimidine derivatives 3-16....

Smelling salts.

I was delving into some reference material recently, trying to track down details of early treatment of mild head injury, and I was struck by the repeated mention of smelling salts as a folk remedy for this problem. But just what are smelling salts? Do they work and can they cause injury? Although smelling salts have recently undergone a resurgence of interest by athletes as a pre-game stimulan...

Synthesis and characterizations of pyridinium salts including poly(pyridinium salt)s and their applications

Poly(methyl methacrylate)s with pendant calixpyrroles: polymeric extractants for halide anion salts.

Poly(methyl methacrylate)s containing pendant octamethylcalix[4]pyrrole subunits were prepared and demonstrated to be capable of extracting tetrabutylammonium chloride and fluoride salts from aqueous media.
