Palladium-Catalyzed Aerobic Oxidative Carbonylation of Amines Enables the Synthesis of Unsymmetrical N,N′-Disubstituted Ureas

A ligand-free palladium-catalyzed aerobic oxidative carbonylation of amines for the synthesis of ureas, particular unsymmetrically N,N′-disubstituted ureas, which cannot be accessed by any other palladium-catalyzed oxidative carbonylation of amines to date, is presented. An array of symmetrical and unsymmetrical ureas were straightforwardly synthesized by using inexpensive, readily available, stable, and safe amines with good to excellent yields under a pressure of 1 atm. This novel method employs oxygen as the sole oxidant and offers an attractive alternative to transition-metal-based oxidant systems.

Simple preparation method of N-acyl compound

The invention relates to a simple preparation method of an N-acyl compound. The simple preparation method comprises the specific steps that an amine compound and R-OCF3 are mixed in a solvent and react for 1 min-48 h at -80-100 DEG C, after the reaction is completed, water is added for quenching, and column separation and purification or recrystallization and purification are carried out to obtainthe N-acyl compound. According to the simple preparation method of the N-acyl compound, the characteristic that a substance containing trifluorooxygen groups can be decomposed in situ to produce fluorophosgene is utilized, and the substance directly reacts with the amine compound to achieve rapid N-carbonylation of an amines substrate and efficiently prepare a urea derivative and a carbamyl fluoride compound. The simple preparation method of the N-acyl compound has the advantages that the operation is simple, the reaction time is short, the application range of the substrate is wide, no catalysts or additives need to be used, the raw materials are easy to obtain, the product yield is high, the purification is easy, and the required compound can be obtained by using a column chromatographyisolation method or recrystallization.

Effect of successive increase in alcohol chains on reaction with isocyanates and isothiocyanates

The reaction of isocyanates and isothiocyanates with long-chain alcohols, e.g. n-hexanol, n-heptanol and n-octanol, exclusively gave N-aryl-O-alkyl carbamates, while N-aryl-O-alkyl carbamates were formed along with symmetrical 1,3-disubstituted ureas and thioureas when the same reactions were carried out with small-chain alcohols at room temperature without using any solvent.
