Dual dopable poly(phenylacetylene) with nitronyl nitroxide pendants for reversible ambipolar charging and discharging

An electrode-attached layer of poly(phenylacetylene) bearing a pendant nitronyl nitroxide group per repeating unit, obtained by the Rh-catalyzed polymerization of 2-(4-ethynylphenyl)-4,4,5,5- tetramethylimidazoline-l-oxyl 3-oxide, underwent oxidation and

Cascade reactions of Me3Si-substituted imidazolidine-1,3-diols with PbO2, including oxidation of the corresponding diol and subsequent elimination of the trimethylsilyl fragment

It was found that reactions of 2-Me3Si-R-substituted (Si-C sp or Si-Csp2) imidazolidine-1,3-diols with PbO 2 in MeOH are cascade reactions, which involve the oxidation of imidazolidine-1,3-diols into nitronyl ni

Cross-coupling of aryl iodides with paramagnetic terminal acetylenes derived from 4,4,5,5-tetramethyl-2-imidazoline-2-oxyl 3-oxide

2-(Arylylethynylphenyl)-4,4,5,5-tetramethyl-2-imidazoline-1-oxyl 3-oxides 12 and 13 were synthesized by cross-coupling of aryl iodides with 1-alkynes containing the 4,4,5,5-tetramethyl-2-imidazoline-1-oxyl 3-oxide fragment. A procedure was developed for the preparation of 3-and 4-ethynyibenzaldehydes with the use of 2-methylbut-3-yn-2-ol.
