Bis(oxalato)borate Salts as Safe and Fluorine-Free Alternatives to Conventional Supporting Electrolytes for Organic Electrosynthesis. [PDF]
ChemSusChemLithium bis(oxalato)borate (LiBOB) was established as a new tool in the repertoire of the synthetic organic electrochemist. As a sustainable alternative to conventional supporting electrolytes, LiBOB shows high stability and ionic conductivity while in test reactions, product yields are comparable to standard electrolyte systems.

Bulletin of the Korean Chemical Society, EarlyView.Mechanistic studies reveal that hexafluoroisopropanol (HFIP) enables C–Cl activation of propargylic halides by stabilizing ion pairs and enhancing effective Brønsted acidity. This cooperative solvent effect allows access to cationic intermediates and promotes cascade formation of tetrahydroquinolines through cyclization and disproportionation ...
