Prof. Dr. Viatcheslav Jouikov (University of Rennes): Electrochemistry and the group 14 chemistry: recent overlaps

AC Kolloquium
Referent/in: Prof. Dr. Viatcheslav Jouikov
Inhalt:

Electrochemistry has greatly contributed to the development of organic chemistry of many kinds of carbon compounds, both in synthetic and mechanistic aspects. Heavier derivatives of the group 14 received less attention and they have been mostly considered in view of the cathodic coupling of their halo-derivatives to give di(or poly)elemental products or their nucleophilic displacement reactions with electrogenerated nucleophiles, or else exploiting oxidative elimination of trimethylsilyl group providing a carbocation activation of the remaining organic moiety.

With the emerging new areas of research, electrochemistry expands these fields and several recent examples of what it can bring to the group 14 chemistry will be briefly presented. This concerns the development of the concept of long distance multielectron-multicenter bonding in hypercoordinated systems of silicon and germanium, the formation of Si- and Ge-centered radicals in one-electron electrochemical processes (using catalytic electrodes and from the complexes with redox active N-aromatic ligands) or by means of reversed electrochemistry, nucleophilic or radical grafting of silyl groups to the conductive interfaces (a variety of carbonaceous materials and metals), making spin-commutating interfaces and electrochemically driven actuators - "atrane muscles", electrochemical formation of nano-powdered germanium in a chlorine-free process, electrochemical fluorine-free etching of silicon and germanium to produce meso/nano-porous materials, and preparing artificial graphite structures with on-demand interstitial distances.
