A strategy that combines electrochemical synthesis and photoredox catalysis was reported for the efficient synthesis of imines. This approach was demonstrated to be highly versatile in producing various types of imines, including symmetric and unsymmetric imines, by exploring the impact of different substituents on the benzene ring of the arylamine. Additionally, the method was specifically applied to modify N-terminal phenylalanine residues and was found to be successful in the photoelectrochemical cross-coupling reaction between NH -Phe-OMe and aryl methylamines, leading to the synthesis of phenylalanine-containing imines. Therefore, this technique would present a convenient and efficient platform for synthesizing imines, with promising applications in chemical biology, drug development, and organic synthesis.

Membrane proteins are essential bio-macromolecules involved in numerous critical biological processes and serve as therapeutic targets for a wide range of modern pharmaceuticals. Small amphipathic molecules, called detergents or surfactants, are widely used for the isolation and structural characterization of these proteins. A key requirement for such studies is their ability to maintain membrane protein stability in aqueous solution, a task where conventional detergents often fall short.

Various electron-donating groups (EDGs) and electron-withdrawing groups (EWGs) were introduced at one ester group position, yielding 12 A series compounds with emission wavelengths spanning from 440 to 578 nm. EDGs led to blue-shifts, while EWGs induced red-shifts relative to the symmetric parent compound.

A novel approach for the S-S bond exchange reaction of two symmetrical disulfides, promoted by TfOH under metal-free conditions at room temperature, has been developed. This protocol facilitates the efficient and effortless synthesis of a series of important unsymmetrical disulfides with yields of up to 93% and excellent functional group compatibility. The advantages of this strategy include straightforward operation, broad substrate scope, good functional group tolerance, high chemoselectivity, and the ability to operate under ambient conditions.

We herein report a modular strategy for the Pd-catalyzed synthesis of diverse phenyl-1,3-dienes from vinyl ethylene carbonate (VEC) and phenylboronic acids. The key feature of this work is that the VEC acts as a diene surrogate upon decarboxylation, which paves the way for the formation of π-allylpalladium intermediates. These intermediates are intercepted by phenylboronic acid, resulting in symmetric diphenylbutadiene and 1-phenylbutadiene, along with unsymmetric products.

The arylation of isonitriles by diaryliodonium salts under photoredox conditions has been proposed for the first time. The suggested procedure allows preparing a broad range of benzamides using both symmetric and unsymmetric diaryliodonium salts under mild conditions. A plausible mechanism for the reaction and the selectivity of aryl transfer (in case of unsymmetrical iodonium salts) were studied.
