Solvent-free condensation of methyl pyridinium and quinolinium salts with aldehydes catalyzed by DBU

Methylpyridinium and methylquinolinium salts were condensed under solvent-free conditions with aromatic aldehydes in the presence of 1,8-diazabicyclo[5.4.]undec-7-ene (DBU) as catalyst, by grinding at room temperature. The products are dyes or useful intermediates. The DBU can be easily recycled and reused. Taylor & Francis Group, LLC.

Interaction of Solvent with the Ground and Excited State of 2- and 4--1-alkylpyridinium Iodides: an Absorption and Fluorescence study

The absorption and emission characteristics of four organic salts: 4--1-alkylpiridinium iodides 1-3 (alkyl: 1 = methyl, 2 = ethyl, 3 = isopropyl) and 2--1-methylpiridinium iodide 4, in various solvents have been studied.It was found that these salts emit a single emission band which is dependent on the solvent's hydrogen bonding and polarity.In polar solvents a marked hypsochromic shift in absorption was observed, while no solvatochromism was observed in the emission spectra.A mechanism is proposed to explain these observations.In the salts 1-3 alkyl substitution on the pyridinium ring d oes not produce significant changes in their spectral properties.Acceptable correlations were obtained for the singlet excitation energies with the redox-potential differences of dyes 1-4. - Keywords: Absorption; emission; hydrogen-bonding; solvatochromism; redox-potential.
