- METHOD FOR PRODUCING CARBAMATE
-
PROBLEM TO BE SOLVED: To provide a method for producing carbamate in which a high yield can be obtained and the amount of by-products produced can be reduced. SOLUTION: In the method, carbamate is synthesized using at least one member selected from the group consisting of amine and derivative thereof, alcohol having 3 or more carbon atoms and carbon dioxide as a raw material, cerium oxide as a catalyst, and 2-cyanopyridine as a dehydrating agent. By using an alcohol having 3 or more carbon atoms, a high yield can be obtained and the amount of by-products produced can be reduced. In addition, the pressure of carbon dioxide can be lowered and the production can be of ease. SELECTED DRAWING: Figure 1 COPYRIGHT: (C)2018,JPO&INPIT

- Copper-catalyzed carbonylation of anilines by diisopropyl azodicarboxylate for the synthesis of carbamates
-
A Cu-catalyzed efficient methodology for the direct carbonylation of anilines has been developed. The N-H bond cleavage and N-C bond formation were notably achieved under solvent-free conditions and a variety of carbamates were synthesized from readily available anilines using diisopropyl azodicarboxylate (DIAD) as the carbonylating source.

- Synthesis of aryl carbamates via copper-catalyzed coupling of aryl halides with potassium cyanate
-
Coupling of aryl halides with potassium cyanate takes place at 100-110 °C in alcohols under the catalysis of CuI (cuprous iodide) and 2-(2,6-dimethylphenylamino)-2-oxoacetic acid, affording the corresponding aryl carbamates with great diversity. Copyright

- Reduction of Nitroarenes to Anilines in Basic Alcoholic Media
-
Substituted nitrobenzenes are reduced by alkoxide ions in alcohols to the corresponding azoxy and aniline derivatives.The reaction leading to anilines has been investigated in detail.Two different processes have been identified, both initiated by the condensation between the nitrosoarene intermediate (the first product of the reduction reaction) and the product of oxidation of the solvent.The imino derivative thus formed (ArN=CH-COR) may either undergo hydrolysis (to aniline) or form, through a series of redox processes, compounds containing the ArNH-CO moiety.These are also hydrolysed to anilines in a slower reaction.
