Synthesis of Poly(thymol) via Oxidative Coupling Polymerization

Anionic oxidative polymerization: the synthesis of poly(phenylenedicyanovinylene) (PPCN2V).

A new polymerization technique that allows for the first-ever synthesis of poly(phenylenedicyanovinylene)s (PPCN2Vs) is described. PPCN2Vs, with their high electron affinities and structural versatility, seem ideally suited to address the need for new n-type polymers. Remarkably the polymers presented herein become more photoluminescent, in the thin film, under continuous irradiation.

Synthesis of conjugated dienes via a biomimetic aerobic oxidative coupling of two C(vinyl)-H bonds.

Synthesis of quinazolines via CuO nanoparticles catalyzed aerobic oxidative coupling of aromatic alcohols and amidines.

CuO nanoparticles were found to be efficient catalysts for the synthesis of quinazoline derivatives; twenty-four products were obtained with good to excellent yields via reaction of N-arylamidines and aromatic aldehydes or benzyl alcohol in air. Neither a base nor an organic oxidant was necessary, and CuO nanoparticles can be recycled without a significant decrease in catalytic activity.

Facile synthesis of dibranched conjugated dienes via palladium-catalyzed oxidative coupling of N-tosylhydrazones.

A facile and highly regioselective Pd-catalyzed oxidative coupling of N-tosylhydrazones providing efficient access to 2,3-disubstituted-1,3-butadienes has been developed. This process features readily available starting materials and mild reaction conditions. Further transformations of the obtained dibranched 1,3-dienes, through Diels-Alder reactions and indene synthesis, are also demonstrated,...

Synthesis of Polypyrrole Coated SnO2-ZnO Electrospun Nanofibers via Vapor Phase Polymerization Method

This paper reports the synthesis of polypyrrole coated SnO2/ZnOelectrospunnanofibers via vapor phase polymerization method. In order to prepare one dimensional (SnO2- ZnO)/polypyrrole with the core sheath structure, first SnO2-ZnO composite nanofibers were synthesized via electrospinning method followed by adsorption of Fe 3+  on the surface of the SnO2-ZnO nanofibers and finally pyrrole w...
