| titleOfInvention | Method for the selective synthesis of cis and trans alkenes by semi-reduction of alkynes catalyzed by water-donating iridium |
| abstract | The invention provides a method for selectively synthesizing cis and trans alkenes by semi-reduction of alkynes catalyzed by water hydrogen-donating iridium. Reaction, react under nitrogen protection to generate cis olefin; conduct the reduction reaction of alkyne with ligand DPPE, catalyst, water and alkyne in organic solvent, and react under nitrogen protection to generate trans olefin; the reactor of reduction reaction is sealed Pressure-resistant reactor, the temperature of reduction reaction is 100～130℃, the time of reduction reaction is 20～48h; the dosage of catalyst is 5～20% of the mole dosage of alkyne, and the dosage of water is 10～50% of mole dosage of alkyne times; the amount of the ligand is 0.2 to 5 times the molar amount of the catalyst. The catalyst system of the invention has extremely high chemical reaction and stereoselectivity, and can synthesize cis or trans olefin products in high yield; the catalyst system has strong universality to substrates, and alkynes containing various functional groups can efficiently A highly selective reduction reaction is carried out. |
