Article Abstract
Herein we disclose a photosensitized →-thermodynamic isomerization of vinyl sulfones, employing SEGPHOS as a promoter. The reaction was performed successfully on 23 vinyl sulfones and was extended to three other olefins. Different mechanistic experiments were performed as well as photophysical studies.

We have established a new route for boron-rich ruthenaborane clusters utilizing [BH·THF] and a ruthenium precursor featuring chelating ligands. Salt elimination reactions between [K(CHNE)], (E = S; Se) and [RuCl(PPh)], afforded -[Ru(κ--CHNE)(PPh)], -- (-: E = S and -: E = Se). Following the ligand exchange reaction with the 1,2-bis (diphenylphosphino)ethane (dppe) ligand yielded -[Ru(κ--CHNE)(dppe)] (-: E = S; -: E = Se).

Alloc-protected furfuryl amino alcohols derived from furfural and ʟ- or ᴅ-valinol were subjected to Torii-type ester electrosynthesis to obtain the corresponding unsaturated esters. These served as key intermediates to prepare ()- and enantioenriched unsaturated amides by -Alloc deprotection which induced concomitant methoxymethyl group cleavage, to- rearrangement, and isomerization of the double bond. An oxazoline ring formation in the resulting unsaturated amides provided the corresponding enantioenriched vinyloxazoline.

Herein, a novel class of azo photoswitches based on a phthalimide with an azo bond to the imide ring is presented, exhibiting reversible isomerization under a broad range of visible light irradiation from 405 to 530 nm. Structural variations with heteroaryl or aryl segments attached to the 3-phthalylazo unit exhibit distinct spectral features, such as red-shifted absorption, well-separated absorption bands, and tunable stability of the metastable isomer, ranging from seconds to days. They differ drastically in the half-life of -isomer stability, ranging from several seconds (-methylpyrrole) to days (-methylimidazole).

Organic molecular glasses are attractive matrices to disperse active ingredients in pharmaceuticals or electronic devices. Typically, they i) have lower glass transition temperatures than inorganic or polymeric glasses, making them easier to process, and ii) are less prone to phase segregation from other organic active materials. However, there is a dearth of functional groups that are known to induce glass formation in preference to crystallization.

The fine-tuning of the (photo)physical properties of molecular photoswitches remains an active area of research, and recently, the incorporation of heterocycles into photoswitch scaffolds has emerged as an effective strategy in this vein. To assess the influence that heterocyclic rings have on hydrazone-based systems, we synthesized a series of photoswitches and examined the impact that heterocycles have on the switching efficiency. TD-DFT calculations and structure-property analyses revealed that heterocycles with basic nitrogen and secondary hydrogen-bonding sites (e.
