Single and Twofold Metal- and Reagent-Free Anodic C-C Cross-Coupling of Phenols with Thiophenes.

Angewandte Chemie (International ed. in English)

Wiebe A, Lips S, Schollmeyer D, Franke R, Waldvogel SR.
PMID: 28967700
Angew Chem Int Ed Engl. 2017 Nov 13;56(46):14727-14731. doi: 10.1002/anie.201708946. Epub 2017 Oct 20.

The first electrochemical dehydrogenative C-C cross-coupling of thiophenes with phenols has been realized. This sustainable and very simple to perform anodic coupling reaction enables access to two classes of compounds of significant interest. The scope for electrochemical C-H-activating cross-coupling...

Talanta. 2000 Jan 24;51(1):145-9. doi: 10.1016/s0039-9140(99)00255-6.

The complex formation between Ba(2+) and different diaza-18-crown-6 ligands has been studied using a new spectrophotometric method. In the presence of undissolved solid ligand the concentration of the dissolved ligand increases in salt containing solutions due to complex formation....
