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 ...

successfully achieved gram-scale synthesis, obtaining a 71% yield of 42 (Fig. 4a). 3 underwent carbonyl α C–H alkylation and esterification ring opening of the saccharin motif (FigS. 4b1 & 4b2), producing 68% and 45% yields of 68 and 69, respectively. Furthermore, deprotection of the...
Amides and Imides Reactivity Profile N-BUTYLUREA is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are le...
Cross-dehydrogenative coupling reactions provide a method to construct new chemical bonds by direct C–H activation without any pre-functionalization. Compared to functionalization of a C–H bond α- to ether oxygen, α- to carbonyl, or at a benzylic pos
A simple, facile and an efficient procedure for the N-sulfonylation of amines, imides, amides and anilides using p-TsCl in the presence of atomized sodium in a mixture of EtOH–THF under sonic condition is developed. The method is rapid, mild and inexpensive; yields are high and the reactio...
