Pd-catalyzed dehydrogenative arylation of arylhydrazines to access non-symmetric azobenzenes, including tetra-ortho derivatives [PDF]

open access: yesBeilstein Journal of Organic Chemistry
Azobenzenes are photoresponsive compounds widely used in molecular switches, light-controlled materials, and sensors, but despite extensive studies on symmetric derivatives, efficient methods for synthesizing non-symmetric analogues remain scarce due to ...

Electrochemical Site-Selective Alkylation of Azobenzenes With (Thio)Xanthenes

open access: yesMolecules, 2022
Herein, we first report an electrochemical methodology for the site-selective alkylation of azobenzenes with (thio)xanthenes in the absence of any transition metal catalyst or external oxidant. A variety of groups are compatible with this electrochemical

Introducing azobenzenes as solid phase peptide synthesis linkers [PDF]

open access: yesRSC Chemical Biology
Orthogonally cleavable linkers are essential tools in solid-phase peptide synthesis (SPPS). We present a fluorogenic C̲o̲umarin-L̲oaded A̲z̲obenzene (COLAZ) linker for SPPS, which offers base and acid stability and a mild reductive cleavage.

Azobenzene protonation as a tool for temperature sensing [PDF]

open access: yesBeilstein Journal of Organic Chemistry
Azobenzenes can be protonated at one of the azo nitrogen atoms, leading to significant changes in their absorption and photochemical properties. While azobenzene protonation has been recently used as a tool in photoswitching studies, the factors ...

Active Ester Functionalized Azobenzenes as Versatile Building Blocks

open access: yesMolecules, 2021
Azobenzenes are important molecular switches that can still be difficult to functionalize selectively. A high yielding Pd-catalyzed cross-coupling method under mild conditions for the introduction of NHS esters to azobenzenes and diazocines has been ...
