Green synthesis method of 1,2,2,6,6-pentamethyl-4-piperidone

The invention discloses a green synthesis method of 1,2,2,6,6-pentamethyl-4-piperidone. 2,2,6,6-tetramethylpiperidone and DMC which serve as raw materials are stirred and reacted at a certain temperature for a certain time under the actions of a solvent and a catalyst, cooling, filtering, concentrating and negative pressure rectification are carried out after the reaction is finished in order to obtain the final product 1,2,2,6,6-pentamethyl-4-piperidone, and yield can reach 90%. Toxic and harmful dimethyl sulfate, chloroform, methyl iodide, formaldehyde, formic acid and the like are not usedin the whole synthesis process, no wastewater is discharged in the production process, and the method is a green synthesis mode of 1,2,2,6,6-pentamethyl-4-piperidone.

Platinum-(phosphinito-phosphinous acid) complexes as bi-talented catalysts for oxidative fragmentation of piperidinols: An entry to primary amines

Platinum-(phosphinito-phosphinous acid) complex catalyzes the oxidative fragmentation of hindered piperidinols according to a hydrogen transfer induced methodology. This catalyst acts successively as both a hydrogen carrier and soft Lewis acid in a one pot-two steps process. This method can be applied to the synthesis of a wide variety of primary amines in a pure form by a simple acid-base extraction without further purification.

Phosphinous Acid Platinum Complex as Robust Catalyst for Oxidation: Comparison with Palladium and Mechanistic Investigations

Secondary phosphine oxides proved to be effective preligands to stabilise a hydroxy-platinum based catalyst that allows the aerobic/anaerobic oxidation of challenging substrates. Kinetic comparisons showed that this system is more efficient and stable than previously reported similar palladium-based catalysts. A neutral platinum dimer bearing bridging hydroxy ligands has been isolated and fully characterised by X-ray diffraction and its involvement in the mechanism has been evidenced by mechanistic studies.
