In this work we have found, that the water-soluble cis,mer-[IrH2Cl(mtppms)3] (mtppms = monosulfonated triphenylphosphine Na-salt) was an excellent catalyst for reduction of terminal alkynes by hydrogen transfer from aqueous HCOOH/HCOONa mixtures. The conversions strongly depended on pH reaction mixtures, and highest rate phenylacetylene hydrogenation observed at 3. same dihydrido-Ir(III) comple...

The use of a modern homogeneous metal complex catalyst for the hydration acetylenes is being investigated. process relevant both industry basic organic synthesis and perfume industry. analysis existing processes used in production acetaldehyde was carried out. Significant shortcomings are revealed: low environmental friendliness high energy consumption. To solve this problem, reaction an acetyl...

The exciton scattering (ES) approach is an efficient tool to calculate the excited states electronic structure in large branched polymeric molecules. Using the previously extracted parameters, we apply the ES approach to a number of phenylacetylene-based test molecules. Comparison of ES predictions with direct quantum chemistry results for the excitation energies shows an agreement within sever...

Raman spectra of the νS(CtC) stretching mode of phenylacetylene (PA) dissolved in acetonitrile and methylcyclohexane have been recorded at 77 K and compared with spectra in the liquid solutions at room temperature [Kołodziejski, M.; Waliszewska, G.; Abramczyk, H. J. Phys. Chem. A 1998, 102, 1918]. Substantial narrowing of spectra in frozen matrices at low temperatures leads to revealing of vibr...

Molecular self-assembly is considered as a promising way to control the manufacture of new materials and their integration into hybrid devices with novel properties. In this work we have synthesized a fulleropyrrolidine bearing a phenylacetylene moiety via the Prato reaction. The characterization of the fulleropyrrolidine by nuclear magnetic resonance and optical spectroscopy is reported, and i...
