Hydrogen-bonding chain and dimer motifs in pyridinium and morpholinium hydrogen oxalate salts
We present here three compounds consisting of pyridinium or morpholinium hydrogen oxalates, each displaying different hydrogen-bonding motifs, resulting in chains for 4-(dimethylamino)pyridinium hydrogen oxalate 0.22-hydrate, C7H11N2+·C2HO4−·0.22H2O (1),

Influence of molecular structure on the antimicrobial function of phenylenevinylene conjugated oligoelectrolytes. [PDF]
Conjugated oligoelectrolytes (COEs) with phenylenevinylene (PV) repeat units are known to spontaneously intercalate into cell membranes. Twelve COEs, including seven structures reported here for the first time, were investigated for the relationship ...

Reaction of Pyridinium Salts with Active Methylene Compounds
The carbon-carbon bond-forming reactions of 1-methyl-2-methylthiophenylpyridinium iodides with active methylene compounds (such as dimethyl malonate, malononitrile) using NaH as a base gave the 2-substituted methylene-1,2-dihydropyridine derivatives.
