OXIDATION OF TERMINAL OLEFINS BY HYDROGEN-PEROXIDE CATALYZED BY TETRAKIS(TRIPHENYLPHOSPHINE)PALLADIUM(O)
No full textTerminal olefins can be oxidised under mild conditions in excellent yields and selectivities to methyl ketones by employing an aqueous medium containing hydrogen peroxide as the oxidant and tetrakis(triphenylphosphine)palladium(0) as the catalyst
Electrochemically induced N-alkylation of pyrroles
No full textElectrochemically generated tetraethylammonium peroxydicarbonate (TEAPC) and tetraethylammonium carbonate (TEAC) react under very mild conditions with pyrroles affording, after addition of a suitable alkylating agent, the corresponding N-alkylated pyrroles in high yields. C-Alkylated pyrroles have not been isolated in any case reported
Bis(ethynyl)-polymers. Part III. Physico-chemical characterization of Poly(2,5-thiophenediyl)ethynylene and Poly[ethynylene(2,5-thiophenediyl)ethynylene]
No full textPoly(2,5-thiophenediyl)ethynylene and poly[ethynylene(2,5-thiophenediyl)ethynylene], synthesized in our lab., have been investigated in order to characterize their physicochem. properties. The optical and IR spectra of the two polymers were studied as well as their thermal properties by means of differential scanning calorimetry and thermogravimetric anal. The elec. cond. of the two polymers in the pristine state and in the I2-doped one has been measured and the effects due to the doping on the spectroscopic and thermal properties have been studied
