A general oxyalkylation of terminal alkynes enabled by iron catalysis has been developed. Primary and secondary alkyl iodides acted as the alkylating reagents and afforded a range of α-alkylated ketones under mild reaction conditions. Acetyl tert-butyl peroxide (TBPA) was used as the radical relay precursor, providing the initiated methyl radical to start the radical relay process. Preliminary mechanistic
已经开发了通过铁催化实现的末端炔烃的一般氧基烷基化。伯和仲烷基碘充当烷基化试剂,并在温和的反应条件下提供一系列α-烷基化的酮。乙酰基叔丁基过氧化物(TBPA)用作自由基中继前体,提供引发的甲基自由基以启动自由基中继过程。进行了初步的机理研究,并对天然产物衍生物进行了后期功能化。
