New enamines and quaternary salts of 5-nitro-2-vinylfuran were obtained by reaction of 1-bromo-2-(5'-nitro-2'-furyl) ethylene with secondary and tertiary amines. The trans conformation of the investigated compounds was established by means of their IR, UV, and PMR spectra and dipole moments.

Polymeric nitrofuran derivatives have been synthesized by chemical modification of macroporous styrene-divinylbenzene copolymers with low molecular weight nitrofurans. The 5-nitrofuryl groups are covalently attached to the polymeric carrier by azomethine, ester, N-alkyl, and sulfamide links, respectively. Comparative hydrolysis studies and biological tests of the modified resins suggested that the polymeric carrier-bound nitrofurans are antimicrobially active. The polymeric nitrofurans have been characterized by IR and "C-solid-NMR spectroscopy".

The radical homopolymerization of 5-nitrofurfuryl methacrylate (NFMA) and the copolymerization of NFMA with methyl methacrylate and various vinyl monomers, respectively, have been studied in dimethylformamide at 65°C. NFMA and poly(NFMA) have been characterized by 1H-NMR, IR, and UV spectroscopy. The influence of polymerization conditions on monomer conversion and on the molecular weight of the polymers obtained has been investigated. The thermal behavior of the polymers obtained has been studied by TGA and DSC analysis.

A number of heterocyclic aldehydes were transformed via their NN-dimethythydrazones to nitriles in high yields using a one-pot procedure.
