Applying optimal Ni-nanostructured catalyst, N-alkylation of aromatic and heterocyclic primary amides with different aldehydes in presence of molecular hydrogen was performed to access structurally diverse N-alkylated amides in good to excellent yields. In addition, the applicability of this N-alkylation ...

Ruthenium chloride and ruthenium carbonyl are efficient catalysts for the N-alkylation of amides, imides and lactams by alcohols. Mono- and di-alkylation occur depending on the conditions. The method is of general applicability with the exception of C1 products (formamide or methanol). The mechanism...
Tab.2 Comparison of NBP yield under different acid intensities Al2O3@Zr(OH)4-Ni(OH)2几乎没有催化活性,γ-Al2O3表现出较低的催化活性,NBP得率为25.6%,固体超强酸Al2O3@Zr(OH)4-Ni(OH)2展示了最高的催化活性。由此可以确定1,4-丁内酯和...
