Angewandte Chemie, EarlyView.An iron‐photocatalyzed unsymmetrical 1,2‐hetero(atom)difunctionalization of alkenes enables to install orthogonal C–Cl and C–O (alkoxyamine) handles which provides access to diverse nucleophiles via complementary reactivity (SN and photoredox) at two distinct sites. Detailed mechanistic studies elucidate interesting features of the iron catalytic cycle.

From Stilbenes to carbo‐Stilbenes: an Encouraging Prospect
Chemistry – A European JournalAbstractBeyond previously described carbo‐naphthalene and carbo‐biphenyl, a novel type of bis‐carbo‐benzenic molecules is envisaged from the stilbene parent. The synthesis, structure, spectroscopic and electrochemical properties of two such carbo‐stilbenes are described at complementary experimental and computational DFT levels. In the selected targets,

Cyclization Pathways of a (Z)-Stilbene-Derived Bis(orthoquinone monoketal)
, 2016 Lead tetraacetate mediated oxidation of a (Z)-bisphenolic stilbene derivative affords a bis(orthoquinone monoketal) product. Thermolysis studies of this highly unsaturated dione reveal that sigmatropic hydrogen shifts, followed by either of two distinct ...

TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces
Angewandte Chemie, EarlyView.A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...
