This study employed dual-functional Cu(triNHC) (triNHC = tri-N-heterocyclic carbene) catalysts for the efficient coupling of CO2 with alcs. and amines to form various carbonates and carbamates with good yields. The direct synthesis of carbonates and carbamates from CO2 was realized by the Cu(triNHC)-catalyzed carboxylative cyclization of CO2 and propargyl alc. and subsequent reactions with an addnl. nucleophile (alcs. or amines). The free carbene dangled from the Cu(triNHC) catalysts deprotonated the propargyl alc. to increase the nucleophilicity toward CO2 and the subsequent cyclization was accelerated by the coordination of the copper ion of Cu(triNHC). This dual function of Cu(triNHC) is critical to the reaction of α-alkylidene carbonates with nucleophiles, forming carbonates or carbamates. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Recommanded Product: (4-Methoxyphenyl)methanol).
(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Recommanded Product: (4-Methoxyphenyl)methanol
