Bis-[4-(R-amino)-1-pyridinium]alkanes are prepared by reacting a 4-(R-amino)pyridine with an appropriate disubstituted alkane. The compounds are useful as antimicrobial agents. Certain species are also useful as dental plaque-preventive agents.

chelating alkylphosphines for the amination of heteroaryl and aryl chlorides, bromides, and iodides. In the presence of this catalyst, aryl and heteroarylchlorides, bromides, and iodides react with many primary amines in high yields with part-per-million quantities of palladium precursor and ligand. Many reactions of primary amines with both heteroaryl and aryl chlorides, bromides, and iodides occur to

New bispyridinium dichlorides based on 2,2-bis(hydroxymethyl)propane-1,3-diyl spacer were synthesized from pentaerythritol, 4-aminopyridine, and carboxylic acids. The resulting biocides possess a high antibacterial effect. The minimal inhibitory concentration (MIC) of these compounds against pathogenic bacteria, namely, gram-positive Methicillin-resistant Staphylococcus aureus (strain ATCC 25923) and
