Direct Metal‐ and Reagent‐Free Sulfonylation of Phenols with Sodium Sulfinates by Electrosynthesis

2019

A novel electrochemical strategy for the synthesis of aryl sulfones by direct sulfonylation of phenols with sodium sulfinates has been developed. The C,S-coupling products are of particular interest for chemical synthesis, material sciences and pharmaceutical sciences. By using this metal- and reagent-free electrochemical method, aryl and diaryl sulfones can be obtained directly in good yields. The established one-step protocol is easy to perform, scalable, inherently safe, and enables a broad scope, which is not limited by quinoid-forming substrates.

The Role of Side-Arms for Supramolecular Affinity Materials Based on 9,9′-Spirobifluorenes

2017

An eightfold functionalized D2d-symmetric 9,9' spirobifluorene was condensed with a collection of diketones with elaborated structural features to form three-dimensional supramolecular architectures with active surfaces. Gas sorption measurements by quartz crystal microbalances revealed remarkable indications about the molecular interactions for the application as affinity materials for the detection of volatile organic compounds. Single-crystal X-ray structure analysis further gave insight by packing motifs and for potential host-guest interactions.

Electrochemical oxo-functionalisation of cyclic alkanes and alkenes using nitrate and oxygen

2023

Abstract Direct functionalization of C(sp3)–H bonds allows a fast, synthetic access to valuable products, starting from simple petrochemicals. Chemical transformation of inactivated methylene groups, however, remains challenging for organic synthesis. Here, we present a general electrochemical method for the oxidation of C(sp3)–H and C(sp2)–H bonds, in which cyclic alkanes and (cyclic) olefins are converted into cycloaliphatic ketones as well as aliphatic (di)carboxylic acids. This resource-friendly method is based on nitrate salts in a dual role as anodic mediator and supporting electrolyte, which can be fully recovered and recycled. Reduction of molecular oxygen as cathodic counter reacti…
