The invention discloses a method for synthesizing trans-cyclohexanedimethanamine, comprising steps of reacting cyclohexene oxide and methylamine aqueous solution under the catalysis of boric acid, and then adding sulfuric acid, dewatering to form an ester, ring-closing under alkaline conditions, adding methylamine aqueous solution and boric acid for hermetic reaction, and distilling to obtain trans-cyclohexanedimethanamine. The synthetic process is simple to perform, provides facilitated isolation and purification and high yield and product purity, and is suitable for batch production.

The role of chelating diamine ligands in the Goldberg reaction: A kinetic study on the copper-catalyzed amidation of aryl iodides

The mechanistic details of the Cu-catalyzed amidation of aryl iodides are presented. The kinetic data suggest that the diamine ligand prevents multiple ligation of the amide. The formation of an amidocuprate species external to the catalytic cycle helped to rationalize the dependence on diamine concentration and the inverse dependence on amide concentration at low diamine concentrations. The intermediacy of a Cu(I) amidate was established through both its chemical and kinetic competency. Copyright
