Copper‐Mediated Decarboxylative Amidination: Synthesis of O‐Methyl‐N‐Alkylnitroisoureas
摘要:
Copper‐catalyzed decarboxylation of peroxides in the presence of O‐methyl‐N‐nitroisourea provides an access to O‐methyl‐N‐alkylnitroisoureas, an underdeveloped class of nitrogenated compounds, which can be regarded as isocyanate surrogates and find useful as AB‐type monomers, for polyurethane synthesis.

alkylating reagents, alkyl etherification of olefins with generalalkyl groups has not been previously reported. In this work, a variety of alkyl diacyl peroxides and peresters generated from aliphatic acids have been found to enable the first iron‐catalyzed alkyl etherification of olefins with generalalkyl groups. Primary, secondary and tertiary aliphatic acids are suitable for this reaction, delivering products

A copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction for the synthesis of 1,4-disubstituted 1,2,3-triazolesfrom alkyl diacyl peroxides, azidotrimethylsilane, and terminalalkynes is reported. The alkyl carboxylic acids is for the first time being used as the alkyl azide precursors in the form of alkyl diacyl peroxides. This method avoids the necessity to handle organic azides, as they are

A CuI-catalyzed cross-coupling of alkyl- and phosphorus-centered radicals for C(sp3)–P bondformation is introduced. Diacyl peroxides, generated in situ from aliphatic acids and H2O2, serve as a source for alkyl radicals and also an initiator for the generation of phosphorus radicals from H–P(O) compounds.
