Synthesis of Oxazolidinone and Tosyl Enamines by Tertiary Amine Catalysis

Dynamic Covalent Chemistry of Aldehyde Enamines: BiIII‐ and ScIII‐Catalysis of Amine–Enamine Exchange

The dynamic exchange of enamines from secondary amines and enolizable aldehydes has been demonstrated in organic solvents. The enamine exchange with amines was efficiently catalyzed by Bi(OTf)3 and Sc(OTf)3 (2 mol %) and the equilibria (60 mm) could be attained within hours at room temperature. The formed dynamic covalent systems displayed high stabilities in basic environment with <2 % by-prod...

Novel synthesis of enamines by iridium-catalyzed dehydrogenation of tertiary amines.

A novel route to enamines is reported, the dehydrogenation of tertiary amines catalyzed by a "pincer-ligated" iridium catalyst.

Tertiary amine mediated aerobic oxidation of sulfides into sulfoxides by visible-light photoredox catalysis on TiO2.

The selective oxidation of sulfides into sulfoxides receives much attention due to industrial and biological applications. However, the realization of this reaction with molecular oxygen at room temperature, which is of importance towards green and sustainable chemistry, remains challenging. Herein, we develop a strategy to achieve the aerobic oxidation of sulfides into sulfoxides by exploring ...
