Herein, a novel and efficient protocol that enables the direct synthesis of amides via heterogeneous manganese-oxide-catalyzed successive cleavage and amidation of C-C bonds in alcs was reported. A wide range of primary and secondary alcs., 1,2-diols, and even β-O-4 and β-1 lignin model compounds can undergo C-C bond cleavage smoothly to deliver one- or multiple-carbon shorter amides. Moreover, a slight modification of reaction conditions allows for the cleavage and cyanation of alcs. to access sterically hindered nitriles. Detailed characterizations and d. functional theory (DFT) calculations indicate that high sp. surface area, abundant oxygen vacancies, and moderate acid sites contribute to the high catalytic performance of the manganese oxides. In the part of experimental materials, we found many familiar compounds, such as 2-(2-Hydroxyethyl)pyridine(cas: 103-74-2Recommanded Product: 103-74-2)
2-(2-Hydroxyethyl)pyridine(cas: 103-74-2) belongs to pyridine. Pyridine is a relatively complex molecule and exhibits a number of different bands in IR spectra. Among others, the bands characterizing the ν8a and ν19b modes have been found to be sensitive to the coordination or protonation of the molecule. Note that the band that is diagnostic for the PyH+ ion at about 1545 cm− 1 (ν19b mode) does not overlap with any of the other bands.Recommanded Product: 103-74-2
