Dual Ligand‐Enabled Nondirected C─H Olefination of (Hetero)Arenes for the Synthesis of Clickable Derivatives

Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
We report an efficient method for late‐stage installation of “clickable” alkyne groups into diverse (hetero)arenes. Using a dual‐ligand palladium catalyst that combines an NASA ligand with an N‐heterocycle, an acrylate unit bearing a terminal alkyne can be introduced via nondirected C─H activation.

Metal‐Catalyzed C(sp2)–H Bond Functionalization of Indolinone‐ and Indanone‐Type Chemical Platforms En Route Toward Late‐Stage Functionalization

Advanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
An in‐depth survey dealing with the aromatic C—H bond functionalization of biologically‐relevant scaffolds featuring the indolinone and indanone core is discussed as they are unique aromatic scaffolds that are 1,2‐doubly fused with small five‐membered rings.

Mechanochemical Difluorocarbene‐Mediated C(sp3)–N Bond Cleavage and In Situ Formylation of Tertiary Amines

Advanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
A sustainable mechanochemical method for C(sp3)–N bond cleavage and in situ N‐formylation of tertiary amines is developed using a difluorocarbene precursor. The transformation proceeds under mild ball‐milling conditions, demonstrating a broad substrate scope, excellent functional group tolerance, and efficient conversions of diverse aliphatic and ...
