This invention discloses a synthetic chiral N -benzoyl- N The method for synthesizing dihexylamino-thio-phenyl sulfoxide imine belongs to the field of organic synthesis. Starting with sodium benzenesulfinate, a key intermediate, chlorosulfoxide imine, is obtained through a multi-step reaction. Then, the following steps are employed: A) an asymmetric chloro-fluorine exchange reaction at a hexavalent sulfur center yields an optically active fluorinated sulfoxide imine, which undergoes a nucleophilic substitution reaction with di-n-hexylamine to give the R-type product; B) using a bifunctional small organic molecule catalyst, 4-arylpyridine N-oxygenate, as the catalytic system, a nucleophilic substitution reaction is carried out with di-n-hexylamine to asymmetricly synthesize the S-type product. This method is characterized by mild conditions, simple steps, high overall yield, and chiral product. N -benzoyl- N Dihexylamino-thiophenyl sulfoxide imine exhibits micromolar levels of biological activity in human lung cancer cells.

This invention belongs to the field of printed electronics technology and relates to a conductive copper paste and its laser sintering process. The conductive copper paste contains micron-sized copper powder, copper ligands, and a solvent; the copper ligands are formed by the coordination of anhydrous copper formate with amino ligands; the amino ligands are one or more selected from hexylamine, 2-ethylhexylamine, butylamine, β-alanine, glycine, 2-amino-2-methyl-1-propanol, octylamine, and oleylamine. The laser sintering process involves printing the conductive copper paste onto the surface of a substrate, then sintering it using a picosecond or femtosecond pulsed laser system under an atmosphere of air, nitrogen, inert gas, or reducing gas. During sintering, the laser scanning program is controlled by software to perform multi-path scanning of the sample surface. This invention solves the problems of existing technologies that require additional atmosphere control equipment, increase production costs, and that a closed atmosphere limits process openness and large-scale continuous production.
