A radical decarboxylation/annulation of acrylamides with aliphatic acyl peroxides was developed, giving a series of linear alkylated oxindoles in moderate to good yields. The reaction used aliphatic acyl peroxides as the linear alkyl radical source and tolerated a broad scope of substrates under metal-free conditions, offering a simple and efficient approach toward alkylated oxindoles.

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.
介绍了一种 Cu I催化的以烷基和磷为中心的自由基的交叉偶联,以形成 C(sp 3 )-P 键。由脂肪酸和 H 2 O 2原位生成的二酰基过氧化物可作为烷基自由基的来源,也是从 H-P(O) 化合物生成磷自由基的引发剂。

A decarboxylative alkylation of enamides with alkyl diacyl peroxides induced by visible-light is described. The chemo-, regio- and stereoselective olefinic β-C–H alkylation generates a series of primary- and secondary alkylated enamides in yields up to 95%. This transformation bears the advantages of operational simplicity, good functional group compatibility and mild conditions.
