Another exciting area of research involves the use of borenium ions, which are strong Lewis acids. Recent advances have shown that with the right supporting ligands, borenium ions can act as ...

This reaction is shown below. In this reaction the ferric ion (Fe 3+) is acting as a Lewis Acid and the oxalate anion (C 2 O 4 2-) as a Lewis Base. A Lewis Acid is an electron pair acceptor and a ...
