It is textbook knowledge that carboxamides benefit from increased stabilisation of the
electrophilic carbonyl carbon when compared to other carbonyl and carboxyl derivatives …

Pyridines are among the most prevalent heterocyclic structural units in pharmaceutical and
agrochemical targets, as well as in materials science (Figure 1). 1 Pyridines also provide …

A novel, one-step N-dehydrogenation of amides to enamides is reported. This reaction
employs the unlikely combination of LiHMDS and triflic anhydride, which serves as both the …

Sulfonium salts are playing an increasingly significant role in contemporary organic
synthesis. In particular, the generation of radicals from sulfonium salts is a fundamental …

The nucleophilic addition of carbon nucleophiles to amides has traditionally been a difficult
task, both due to reactivity and selectivity problems. When successful, these processes …

Site‐selective functionalization of C− H bonds in small complex molecules is a long‐
standing challenge in organic chemistry. Herein, we report a broadly applicable and site …

The electrophilic activation of amides, especially by the action of trifluoromethanesulfonic
(triflic) anhydride, enables the formation of highly electrophilic and reactive intermediates …

Trifluoromethanesulfonic anhydride has been widely used in synthetic organic chemistry,
not only for the conversion of various oxygen‐containing compounds to the triflates, but also …

Amines are an important class of compounds that constitute the major body of bioactive
natural products (alkaloids) and pharmaceuticals.[1] Amides are a class of easily available …

Magnetite-sulfonic acid (Nanocat-Fe-OSO3H), prepared by the wet-impregnation method,
serves as a magnetically retrievable sustainable catalyst for the Ritter and multicomponent …
