N-alkylation of amide, imide, and lactams in solid-liquid phase transfer catalysis using PEG-400 as catalyst in the presence of potassium hydro- xide or carbonate afforded various N-alky1ated products in good yields. This econom- ic method has the advantages of mild reaction condition and conv...

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 C 1 products (formamide or methanol). The ...
The copper-catalyzed selective mono-N-alkylation of primary amides with bis(trialkylsilyl) peroxides as alkylating agents was reported. The results of a mechanistic study suggest that this reaction should proceed via a free radical process that includes the generation of alkyl radicals from bis(tri...

Cu-Fe catalysts prepared from layered double hydroxide (LDH) precursors were applied for the straightforward N-alkylation of aniline with benzyl alcohol in base-and oxidant-free conditions. Among the bimetallic Cu-M catalysts prepared from LDH precursors, the Cu-Fe catalyst showed the most active ...
