Reactivity of δ‐Functionalized Para‐Quinone Methides in Nucleophilic Addition Reactions

Chemistry – A European Journal, EarlyView.
The reactivities of δ‐functionalized para‐quinone methides (pQMs) were characterized by kinetic studies of their reactions with carbanions in DMSO. Evaluating the second‐order rate constants (k2) by the Mayr‐Patz equation gave the electrophilicities E of pQMs.

Sustainable Approaches for the Protection and Deprotection of Functional Groups

Chemistry – A European Journal, EarlyView.
Shield: Protection and deprotection are key to selective synthesis, but conventional methods can lack sustainability. This review highlights electrochemical and photochemical strategies as greener alternatives, emphasizing their mechanisms, functional group tolerance, and broad synthetic utility.

N,N‐Bis(trifluoromethyl)aminoacetonitrile: A Versatile Building Block for the Introduction of the Bis(trifluoromethyl)amino Group

Chemistry – A European Journal, EarlyView.
N,N‐Bis(trifluoromethyl)aminoacetonitrile (CF3)2NCH2CN, which is readily accessible, is established as a versatile starting compound for the synthesis of various types of (CF3)2N‐containing building blocks, that is, N‐heterocycles, alkenes, and acid derivatives such as N,N‐bis(trifluoromethyl)glycine.

A Diverse Array of Catalytic Photoredox Reactions Based on Aluminum(III)‐Salen Complexes: Understanding the Enhancement of Catalytic Activity via Amine Association

Chemistry – A European Journal, EarlyView.
We report the diversity of the photoredox reactions based on Al‐salen catalysts. The combination of an Al‐salen catalyst with an amine under visible‐light irradiation allowed the reductive transformations of aryl chlorides, carbonyl compounds, and perfluoroalkylarenes, and the oxidative transformations of amines.
