WebMentioning: 26 - The chemistry of "frustrated Lewis pairs" (FLPs) has become a rapidly evolving field since it was introduced 6 years ago. It offers new strategies for small molecule activation and organic synthesis which have long been dominated by transition metals. This chapter focuses on the recent development of organoborane compounds and their … WebOct 4, 2024 · Frustrated Lewis pairs (FLPs) combine a Lewis-acidic electron-pair acceptor and a Lewis-basic electron-pair donor. The Lewis acid and the Lewis base in an FLP cannot form an adduct due to steric hindrance. FLPs can activate small molecules, most notably H 2 and CO 2. These reactions are thought to proceed via polar pathways, with …
