With peculiar structural features at the surface of small metal nanoparticles, some discrete sites can display catalytic behaviour similar to what could be observed with mononuclear metal catalysts in solution. We have studied the transfer of two catalytic tandem reactions from homogeneous to heterogeneous conditions. Tandem...

Abstract Targeting RNA with small molecules is a major challenge of current medicinal chemistry, and the identification and design of original scaffolds able to selectively interact with an RNA target remains difficult. Various approaches have been developed based on classical medicinal chemistry strategies (fragment‐based drug design, dynamic...

This study valorises the benign epoxidation of (R)-(+)-limonene to generate novel bio-resourced limonene dioxide monomers. Without additional steps of separation or functionalization, the racemic limonene dioxide was cured with glutaric and dimethylglutaric anhydrides leading to thermosets with high Tg (~98 °C) and good mechanical properties (σ...

The coordination chemistry of the anionic NHC 1– based on an imidazo[1,5-a]pyridin-3-ylidene (IPy) platform substituted at the C5 position by an anionic barbituric heterocycle was studied with d6 (Ru(II), Mn(I)) and d8 (Pd(II), Rh(I), Ir(I), Au(III)) transition-metal centers. While the anionic barbituric heterocycle is planar in the...

The synthesis and characterization of original NHC ligands based on an imidazo[1,5-a]pyridin-3-ylidene (IPy) scaffold functionalized with a flanking barbituric heterocycle is described as well as their use as tunable ligands for efficient gold-catalyzed C−N, C−O, and C−C bond formations. High activity, regio-, chemo-, and stereoselectivities...

When dealing with industrial plastics (polymers plus additives), most approaches are using marketed materials where the polymer is identified, but not the additives. Additives used in plastics are incorporated at various stages of the synthesis and compounding by different companies which are not disclosing their recipes. In the present work, a...
