Piperidinodechlorination of chloro nitro naphthalenes. Further comparison between nitro-group and aza-group activation

The importance of specific solvation (H bonding) in the nucleophilic reactions of N-heteroaromatic substrates has been stressed in recent studies and was suggested to be a major differential feature between aza- and nitro-group activation, on the basis of the solvent effects observed in the reaction of 2- and 4- chloroquinoline with piperidine. The most appropriate comparison with the latter reaction requires the investigation of the nitronaphthalene analogs, which is the object of the present note

OXIDATION OF TERMINAL OLEFINS BY HYDROGEN-PEROXIDE CATALYZED BY TETRAKIS(TRIPHENYLPHOSPHINE)PALLADIUM(O)

Terminal 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

Electrochemically generated tetraethylammonium peroxy- corresponding N-alkylated pyrroles in high yields. C- Alkylated pyrroles have not been isolated in any casedicarbonate (TEAPC) and tetraethylammonium carbonate (TEAC) react under very mild conditions with pyrroles reported. affording, after addition of a suitable alkylating agent, th

Bis(ethynyl)-polymers. Part III. Physico-chemical characterization of Poly(2,5-thiophenediyl)ethynylene and Poly[ethynylene(2,5-thiophenediyl)ethynylene]

Poly(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
