New Advances in Chemical Research in 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, and research on the structure and performance of functional materials.In a patent, 22990-19-8, name is 1-Phenyl-1,2,3,4-tetrahydroisoquinoline, introducing its new discovery. Application In Synthesis of 1-Phenyl-1,2,3,4-tetrahydroisoquinoline
The application of bifunctional iron complexes for the hydrogenation of polarized C=X bonds is reported. Two modified Knoelker complexes bearing ionic fragments were synthesized and fully characterized. With these well-defined complexes, the reaction proceeded under mild conditions in pure water, and various alcohols and amines were isolated in good yields. Compared with hydrogenation in organic solvents, better reactivities were observed. Is this the iron age? Well-defined iron-complex-catalyzed reduction of aldehydes, ketones, and imines using molecular hydrogen in water is presented. Under mild conditions, good yields for a broad range of substrates are achieved.
