Despite the ubiquity of singlet carbenes in chemistry, their utility as true monomeric building blocks for the synthesis of functional organic polymers has been underexplored. Here the authors show mono- and bis-acyclic amino(aryl)carbenes selectivel

Four-component coupling reactions between xanthogenates, alkenes, CO, and sulfonyl oxime ethers were studied. In the presence of hexabutylditin, working as a propagating radical reagent, the chain reaction proceeds, as expected, taking into account r

This review article describes the recent development in the chemistry of carbamoyl radicals generated from oxamic acids. This mild and efficient method compares well with previous methods of generation of these nucleophilic radicals. The oxidative de

The PIDA-mediated oxidative decarboxylation of oxamic acids in the presence of alcohols is shown to afford the corresponding urethanes under thermal conditions. Computational and experimental mechanistic exploration allows to rationalize the differen

The Cu-catalyzed C-H activation of alkanes in the presence of O-methyl-N-nitroisourea affords a facile entry to O-methyl-N-alkylnitroisoureas, shelf stable and benign isocyanate precursors. The latter is then readily converted into carbamates and ure
