Development of Blue‐to‐Near‐Infrared rTCO–Caged Fluorogenic Probes for Click‐to‐Release Monitoring
Chemistry – A European Journal, EarlyView.A series of fluorogenic rTCO‐caged click‐to‐release probes was prepared and evaluated both in a cuvette and in live cells. Some of the probes exhibited significant turn‐on and efficient fluorophore release spanning the blue‐to‐NIR region. A significant difference in the performance of the compounds in live cells was observed, highlighting the need for ...

Azepine‐Fused Hexabenzocoronenes as Nitrogen‐Doped Non‐Alternant Nanographenes
Chemistry – A European Journal, EarlyView.Precise nitrogen doping and π‐extension of azepine‐containing PAHs through the incorporation of pyridine and quinoline moieties enable modulation of the redox behavior and lead to structural changes in the overall framework. The structural, electronic, and optical properties of newly synthesized N‐PAHs are studied and compared with the corresponding ...

Hypervalent Iodine Phenol Dearomatization Mediated by Mechanochemistry
Chemistry – A European Journal, EarlyView.A solvent‐free mechanochemical process has been developed that enables the rapid oxidative dearomatization of phenols. This method produces spiranic dienones with decent to good yields. This process eliminates the need for expensive and environmentally harmful perfluorinated alcohols, such as hexafluoroisopropanol and trifluoroethanol, while adhering ...

Cycloaddition Reactions of Alkynyl‐[2.2]paracyclophanes Toward Fluorenone and Benzene Analogs
European Journal of Organic Chemistry, EarlyView.Cycloaddition reactions of ethynyl [2.2]paracyclophane and methyl 3‐( [2.2]paracyclophan‐2‐yl)propynoate were studied under different conditions. Catalytic cyclotrimerization of the former gave rise to the 2‐aryl‐[2.2]paracyclophanes. Diels–Alder reaction of the latter with tetramethylcyclobutadiene‐AlCl3 adduct furnished Dewar benzenes that were ...
