Firming COFs up takes Michael reaction catalysis forward

Chemists stabilise hexagonal layers that form nanochannels, which help speed up conversions

By making formerly fragile covalent organic frameworks (COFs) resistant to harsh conditions, researchers in Japan have created what they think could be a powerful new catalyst concept. Donglin Jiang’s team at the National Institutes of Natural Sciences in Okazaki have already used their chiral COFs to enable selective and high-yielding Michael reactions with low-reactivity ketones. They believe theirs is the first example of a heterogeneous catalyst based on a crystalline porous material used in this reaction.
