The Importance of Metal Ion Impurity Bands in the Photoluminescence of Halide Double Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
Many publications have associated emission spectral features of double perovskite halides in the region at 460–470 nm with “pristine” materials. This leads to not only false observations but also incorrect conclusions concerning the transformation of dark into bright excitons or boosting self‐trapped exciton emission.

Recyclable All‐in‐One Organo‐Photo‐Auxiliaries Enabling (sp3)C−(sp3)C Coupling Reactions with Diverse Functionalities

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Photochemical C−C coupling reactions can be tailored to industrial chemical processes and preparations of pharmaceuticals. Recent approaches in this area are limited to using precious transition metal coordination complexes that facilitate light absorption and redox processes with benchtop chemicals. Herein, we propose a paradigm that involves

Synthesis of spirolactones from carbonyls via carboborylation of N‐sulfonylhydrazones with alkoxycarbonylalkylboronic acids

open access: yesAdvanced Synthesis &Catalysis, Accepted Article.
A straightforward synthesis of spirolactones from carbonyls via N‐tosylhydrazones is described. The process consist in the reaction between the N‐tosylhydrazone and ethoxycarbonylethylboronic acid or ethoxycarbonylpropylboronic acid, leading to spiro γ‐butyrolactones or δ‐valerolactones respectively. The transformation takes place by carboborylation of

Recent Developments in Radical Mediated Synthesis of Organostannanes.

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract The present review aims to provide an overview of the recent developments in the preparation of aryl‐ or alkenyl stannanes via carbon‐ and tin‐centered radicals enabling chemists to synthesize organostannyl derivatives with high efficiency and under mild conditions.
