‡ These authors contributed equally Dedicated to Professor Dieter Enders Abstract A cationic ruthenium(II)-complex enabled unprecedented C–H methylations on indoles and pyrroles. The versatile catalyst proved to be widely applicable and delivered the methylated heteroarenes with excellent levels of positional selectivity and ample substrate scope. The robustness of the catalysts was reflected by the
α-Phosphonovinyl Arylsulfonates: An Attractive Partner for the Synthesis of α-Substituted Vinylphosphonates through Palladium-Catalyzed Suzuki Reactions
A new and attractive coupling partner for the synthesis of α‐substituted vinylphosphonates through Suzuki reactions has been developed. The developed O‐centered electrophiles couple with various organoboron reagents to give α‐substituted vinylphosphonates in moderate to excellent yields. This protocol features broad substrate scope, mild conditions, and high efficiency.

A photoredox catalytic method has been developed for the direct C2 alkylation of pyridineN-oxides. This reaction is compatible with a range of synthetically relevant functional groups for providing efficient synthesis of a variety of C2-alkylated pyridineN-oxides under mild conditions. Mechanistic studies are consistent with the generation of a radical intermediate along the reaction pathway.
