The Azidofunctionalization of Alkenes
ChemistryEurope, EarlyView.The azidofunctionalization of alkenes offers a powerful strategy for synthesizing nitrogen‐containing compounds by installing both an azide and a second functional group in one step. This approach, employing photoredox catalysis, transition metals, and radical methods, is efficient, selective, and versatile, with applications in pharmaceuticals and ...

Photophysical Properties of Substituted Zinc Phthalocyanine‐Dextran Systems
ChemPhotoChem, EarlyView.The self‐assembled ZnPc(COOH)4/DX and ZnPc(COOH)8/DX systems in DMSO/H2O solution show strong absorption in the 400–700 nm wavelength region for anticancer therapy. The ZnPc(COOH)4 exhibits efficient phosphorescence at room temperature, with a quantum efficiency of 14.8% compared to 3.81 % for the conjugated ZnPc(COOH)4/DX system, while the longhest ...

En Route Toward Sustainable Polycarbonates via Large Cyclic Carbonates
ChemSusChem, EarlyView.The use of safe carbonylating agents, allowed by a suitable (bio)catalytic systems, affords the sustainable and green synthesis of large‐ring cyclic carbonates by reaction of renewables such as bio‐based diols. These carbonates are prone to ring‐opening polymerization paving the way for the production of circular aliphatic polycarbonates.
