Modular Access to α‐Tertiary Amines: Electrochemical Tandem Di‐Functionalization of Olefins With Ammonia Surrogates and Amino Acids

Angewandte Chemie, EarlyView.
A metal‐ and oxidant‐free electrochemical multicomponent di‐functionalization strategy that rapidly converts 1,1‐disubstituted alkenes into α‐tertiary primary amines with simultaneous installation of bio‐relevant sulfur or selenium motifs was devised for late‐stage functionalization. ABSTRACT Quaternary carbon centers, especially those bearing nitrogen,

Nitrogen Radical Photocatalysed Reduction of Nitrous Oxide

Angewandte Chemie, EarlyView.
This work offers the first example of reduction of the potent greenhouse gas N2O to the benign products N2 and O(Bpin)2 using a nitrogen‐based catalyst. The active catalyst is shown to be a nitrogen‐based radical which operates under photocatalytic conditions.

Tunable Oxygen Connectivity in Carbaporphyrinoid Polymers on Metal Surfaces

Angewandte Chemie, EarlyView.
Hydroxyl‐functionalized dicarbaporphyrinoid polymers synthesized on Au(111) enable tunable oxygen‐mediated connectivity under UHV conditions. Thermal activation yields one‐dimensional hydroxyl‐terminated polymers that can selectively evolve into either covalently‐linked dibenzo‐p‐dioxane architectures through intermolecular C–O–C coupling or two‐fold ...
