Harnessing Bifunctional N‐Benzoyloxyamides for Photoredox Amidative Dual Functionalizations of Alkenes

open access: yesAngewandte Chemie, EarlyView.
A novel photocatalytic strategy is presented for intermolecular amidative dual functionalization of alkenes using N‐benzoyloxyamides as bifunctional N─O reagents. The method enables efficient olefin 1,2‐amidooxygenation and significantly extends its reactivity to encompass amidoazidation, diamination, and formal anti‐Markovnikov hydroamidation.

Taxonomy of Chemical Bondings: Opportunities and Challenges

open access: yesAngewandte Chemie, EarlyView.
The recent focus on supramolecular and nanosized systems produced a major increase in the types of observed noncovalent interactions and in the diversity of terms used to designate them. A hierarchical categorization (taxonomy) of terms used to designate electrophile···nucleophile interactions is proposed here.
