Transition‐metal‐catalyzed hydroamination reactions are sustainable and atom‐economical CN bond‐forming processes. Although remarkable progress has been made in the inter‐ and intramolecular amination of olefins and 1,3‐dienes, related intermolecular reactions of amides are still much less known. Control of the regioselectivity without analogous telomerization is the particular challenge in the catalytic

An electrochemical epoxidation of unactivated olefins using water as the source of oxygen atoms has been developed. The epoxidation reaction employs seminormal-BrCH2CH2OH as the mediator, which shows good functional group compatibility, and can easily be performed on the gram scale. A wide range of unactivated olefins could be tolerated to give the functionalized epoxides with satisfactory results
