An electrochemical oxidative coupling of anilines to selectively provide azo aromatic compounds by using mild reaction conditions has been investigated. Further, the generality and feasibility developed protocol were showcased synthesizing differently substituted in moderate good isolated yields. Additionally, different control experiments performed investigate mechanism. These indicated formation hydrazobenzene as an intermediate while ruling out possibility nitrobenzene or nitroso-benzene during this transformation.

Abstract Continuous flow synthesis is pivotal in dye production to address batch‐to‐batch variations. However, synthesizing water‐insoluble dyes an aqueous system poses a challenge that can lead clogging. This study successfully achieved the safe and efficient of azo by selecting optimizing reactor modules for different reaction types two‐step implementing cascade cooperation. Integrating continuous microreactor with stirred tank (CSTR) enabled Sudan Yellow 3G without introducing water‐soluble functional groups or using organic solvents enhance solubility. Optimizing conditions (acidity/alkalinity, temperature, residence time) within initial modular resulted remarkable 99.5% isolated yield, 98.6 % purity, rate 2.90 g h −1 . Scaling‐up based on module characteristics further increased 74.4 while maintaining high yield purity. The construction this small 3D‐printing cascaded process scaling‐up provide technical support dyes, particularly high‐market‐share dyes. Moreover, versatile methodology proves applicable processes involving various homogeneous heterogeneous cascades.

Abstract A new type of functionalized BODIPY dyes is described. Utilizing an established procedure for Buchwald–Hartwig reactions, we have been able to convert α-chloro BODIPYs α-azo-BODIPYs using phenylhydrazines. Optimization the reaction conditions and variation core phenylhydrazine were conducted. Absorption emission spectra recorded.
