Active ester functionalized azobenzenes as versatile building blocks

, (2021/07/12)
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 established. Yields were consistently high with very few exceptions. The NHS functionalized azobenzenes react with primary amines quantitatively. These amines are ubiquitous in biological systems and in material science.

The invention relates to a bromofluoro polysubstituted benzaldehyde derivative and a preparation method. The preparation method comprises the following steps: obtaining 2,6-difluoro-4-cyano phenylamine under nitrogen protection by using 2,6-difluoro-4-bro

Azobenzene functionalized with ortho-fluorine atoms has a lower energy of the n-orbital of the Z-isomer, resulting in a separation of the E and Z isomers' n→π* absorption bands. Introducing para-substituents allows for further tuning of the absorption spe
