And the article was included in Synthesis in 2022.Recommanded Product: 2-Methoxyethylamine The following contents are mentioned in the article:
An efficient heterogeneous palladium-catalyzed carbonylative annulation of 2-iodoanilines, tri-Me orthoformate, and amines has been developed. The reaction proceeds smoothly in toluene at 110°C using N,N-diisopropylethylamine (DiPEA) as base and 2 mol% of MCM-41-anchored bidentate phosphine palladium complex [MCM-41-2P-Pd(OAc)2] as catalyst under 10 bar of carbon monoxide and provides a general and practical method for the construction of a wide variety of quinazolin-4(3H)-ones in good to excellent yields from com. easily available starting materials. This heterogenized palladium catalyst can be easily recovered via a simple centrifugation process and reused more than nine times with almost consistent catalytic efficiency. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Recommanded Product: 2-Methoxyethylamine).
2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: 2-Methoxyethylamine
