Homolytic substitution at phosphorus for C–P bond formation in organic synthesis
Beilstein Journal of Organic Chemistry, 2013 Organophosphorus compounds are important in organic chemistry. This review article covers emerging, powerful synthetic approaches to organophosphorus compounds by homolytic substitution at phosphorus with a carbon-centered radical. Phosphination reagents

Advanced Synthesis &Catalysis, EarlyView.Abstract Herein, we present the first light‐mediated, diastereoselective de novo synthesis for 2,3‐substituted indolines, a privileged scaffold in pharmaceuticals. The protocol was tested with various aryl and alkyl groups, maintaining high yields up to 85% across different substituents.

Advanced Synthesis &Catalysis, EarlyView.The impact of olefin backbone substitution in N‐heterocyclic olefin‐substituted phosphines is investigated. While these ligands are highly electron‐donating, their catalytic activity in Pd‐catalyzed CN cross‐coupling reactions decreases as the size of the backbone substituent increases.

Advanced Synthesis &Catalysis, EarlyView.Simple and selective. The electrochemical heterofunctionalization of activated tropones is achieved using readily available inorganic salts. A theoretical model, based on cyclic voltammetry and quantum chemistry calculations, predicts both reactivity trends and site selectivity.
