The synthesis of a series of alpha-aryl or alpha-alkyl functionalised beta-hydroxy and beta-keto esters has been achieved by reacting alpha-diazoesters with boranes, and aldehydes, ketones, anhydrides, nitriles, esters or isocyanates. In a mild react

Summary The chemistry of Lewis acids, in particular that of triarylboranes, has received unprecedented attention in recent years. Particularly in their role as the Lewis acid component of frustrated Lewis pairs (FLPs), boranes have shown astonishing
