The electrochemical conversion of a spruce lignosulfonate into vanillin, at nickel anodes, was explored in previously unobtainable detail. A flow reactor (FM01), in a rig that permitted considerable variation of electrolysis conditions, allowed up to

Electrochemically-generated radical-anions of oxalate esters undergo cleavage. For those of ethyl 4-substituted benzyl oxalates the rates of cleavage have been measured by cyclic voltammetry combined with digital simulation. Consideration of substitu

A systematic investigation of the anodic oxidation in nucleophilic media of 2-methyl and 2-benzylnaphthalenes, substituted at the 6-position in the naphthalene nucleus and at the 4-phenyl position of the benzylic side chain, has been carried out to i

The electrosynthesis of poly(p-xylylenes) (PPXs) and poly(p-phenylenevinylenes) (PPVs) by the direct and mediated cathodic reduction of (halomethyl)arenes is reviewed and, where appropriate, comparisons made with more conventional chemical routes. At

The role of metal complexes as redox mediators in the electrosynthesis of poly(p-xylylenes) (PPXs) has been explored, with a view to designing metal-containing precursors that can act both as mediators and starting materials for metal-containing poly

The electrochemical generation and characterisation of a variety of o-quinodimethanes (o-QDMs) are described together with the outcome of preparative experiments in which they are key intermediates. The quinodimethanes are conveniently formed, in DMF

ortho-Quinodimethanes (o-QDMs) are conveniently generated cathodically in aqueous electrolyte in the presence of N-methylmaleimide, which acts as both redox mediator and dienophile. endo-Diels–Alder adducts are formed efficiently and rapidly and co

Quinodimethanes (QDMs) were generated cathodically from 1,4-bis(halogenomethyl)arenes, either by direct or by mediated reduction, and characterised using cyclic voltammetry in the 0.1 to 200 V s−1 range. Formal redox potentials (E°) were determine
