Design of Narrow-Bandgap Polymers. Syntheses and Properties of Monomers and Polymers Containing Aromatic-Donor and o-Quinoid-Acceptor Units
TL;DR: A series of novel monomers and polymers containing aromatic-donor and o-quinoid-acceptor units was prepared, and the relationship between their spectral and electrochemical properties and their structures was investigated as discussed by the authors.

A General Solution for the 2‐Pyridyl Problem
TL;DR: Problem solved: an air-stable 2-pyridyl borane that can effectively couple to a wide range of aryl and heteroaryl halides and pseudohalides has evaded the synthesis community for decades.

Ester Hydrolysis by a Catalytic Cyclodextrin Dimer Enzyme Mimic with a Metallobipyridyl Linking Group
Biliang Zhang,Ronald Breslow +1 more
TL;DR: In this paper, a β-cyclodextrin dimer with a linking bipyridyl group is synthesized as a catalyst precursor, a holoenzyme mimic, binding both ends of potential substrates into the two different cyclodesxtrin cavities, holding the substrate ester carbonyl group directly above a metal ion bound to the bipyrin unit.
Journal ArticleDOI
Novel synthetic strategy of carbolines via palladium-catalyzed amination and arylation reaction
TL;DR: In this article, four parent carbolines and their corresponding 5- or 9-methylsulfonyl derivatives were synthesized by the palladium-catalyzed intramolecular arylation reaction of ortho-bromo-substituted anilinopyridines.
