A heterogeneous-catalyst-based, microwave-assisted protocol for the synthesis of 2,2'-bipyridines.
A new method of preparing 2,2'-bipyridines with short reaction times by using microwave assistance and heterogeneous catalysts has been developed. With a Negishi-like protocol, it was found that Ni/Al(2)O(3)-SiO(2) afforded 2,2'-bipyridine products in up to 86% yield in 1 h. Palladium supported on alumina also provided yields of 2,2'-bipyridines comparable to those seen for homogeneous PEPPSI (...
متن کاملSynthesis and Electrochemical and Photophysical Characterization of New 4,4′‐π‐Conjugated 2,2′‐Bipyridines that are End‐Capped with Cyanoacrylic Acid/Ester Groups
Two new functionalized 4,4'-disubstituted 2,2'-bipyridines that were end-capped with cyanoacrylic acid or cyanoacrylic acid ester anchoring groups, which might allow their efficient functionalization on TiO2 or other metal-oxide semiconductor surfaces, have been synthesized and characterized by electrochemical, photophysical, and spectroscopic measurements. The electrochemical and photophysical...
متن کاملTowards allosteric receptors – synthesis of β-cyclodextrin-functionalised 2,2’-bipyridines and their metal complexes
Herein, we present three new 2,2'-bipyridines that carry two β-cyclodextrin moieties in different substitution patterns. When coordinated by zinc(II) or copper(I) ions (or their complexes), these compounds undergo conformational changes and switch between "open" and "closed" forms and thereby bringing together or separating the cyclodextrin moieties from each other.
متن کاملSynthesis of highly functionalized 2,2'-bipyridines by cyclocondensation of β-ketoenamides – scope and limitations
The scope of a flexible route to unsymmetrically functionalized bipyridines is described. Starting from 1,3-diketones 1a-e, the corresponding β-ketoenamines 2a-e were converted into different β-ketoenamides 3a-g by N-acylation with 2-pyridinecarboxylic acid derivatives. These β-ketoenamides were treated with a mixture of TMSOTf and Hünig's base to promote the cyclocondensation to 4-hydroxypyrid...
متن کاملA direct route to 6,6'-disubstituted-2,2'-bipyridines by double Diels-Alder/retro Diels-Alder reaction of 5,5'-bi-1,2,4-triazines.
Inverse electron demand Diels-Alder reaction of functionalized 5,5'-bi-1,2,4- triazines with bicyclo[2.2.1]hepta-2,5-diene in boiling p-cymene leads to a range of 6,6'- disubstituted-2,2'-bipyridines in good yield.
