An iron-catalyzed radical alkylazidation of electron-deficient alkenes is reported. Alkyl diacyl peroxides work as the alkyl source, and trimethylsilyl azide acts as the azido reservoir. This method features mild reaction conditions, wide substrate scope, and good functional group tolerance, providing a range of α-azido esters, an α-azido ketone, and an α-azido cyanide in high yields. These azides

are readily accessible from carboxylic acids, are utilized as general primary, secondary, and tertiary alkylating reagents for iron‐catalyzed vinylic C−H alkylation of vinyl arenes, dienes, and 1,3‐enynes. This transformation affords olefinic products in up to 98 % yield with high E/Z values. A broad range of functionalities, including carboxyl, boronic acid, methoxy, ester, amino, and halides, are

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 decarboxylative alkyl esterification of vinylarenes induced by visiblelight is described. A variety of alkyl diacyl peroxides synthesized from readily available aliphatic carboxylicacids are used as not only the oxygenation but also alkylation source. This simple and easy to handle reaction has a wide substrate scope, excellent yields, and works under mild reaction conditions. Carbon dioxide is
