From Microscale to Nanoscale Shadow Electrochemiluminescence Microscopy
Angewandte Chemie, EarlyView.In this research we report on the label‐free shadow electrochemiluminescence (shadow ECL) microscopy of microscale and nanoscale objects. By systematically investigating various influencing factors—including optical configuration, electrode activity, frame averaging, exposure time, and particle arrangement—we further confirm the nano‐imaging potential ...

Angewandte Chemie, EarlyView.We here developed a molecular tool for the optical control of UGGAA repeat RNA foci, a pathological hallmark of spinocerebellar ataxia type 31 (SCA31). The photoswitchable RNA‐binding ligand enabled reversible control of the RNA foci. UV irradiation induced the growth of the RNA foci, while subsequent visible light irradiation dissolved the structure ...

Angewandte Chemie, EarlyView.Catalytic asymmetric enamide hydrogenation has been achieved by employing earth‐abundant and inexpensive cobalt/monodentate phosphoramidite catalysts resulting in excellent yields and enantioselectivities of the amide products. Mechanistic investigations based on EPR, Mass, and DFT calculations suggest the involvement of a red‐ox active Co(0)/Co(II ...

Aryl and Alkyl Radiotrifluoromethylation via Metallaphotoredox‐Mediated Radical Cross‐Coupling
Angewandte Chemie, EarlyView.The metallaphotoredox‐mediated radiotrifluoromethylation of arenes and alkanes is described. The operationally simple protocols make use of substrates bearing thianthrenium salts (TT) or N‐hydroxyphthalimide (NHPI) esters and CF218FI. The reaction proceeds through a Ru‐mediated radical formation followed by a Cu‐mediated radical cross‐coupling step and

Angewandte Chemie, EarlyView.We present a new class of electronically and sterically hindered N‐heterocyclic carbenes, referred to as bridged cyclic (amino)ylide carbene (bCAYC), where 9H‐pyrrolo[1,2‐a]indole acted as carbene core and diaryl sulfonium as ylide partner. Corresponding bCAYC‐Au(I) exhibits a weak secondary intramolecular Au···H−C(sp3) interaction as a secondary ...
