Hydroamidation of olefins constitutes an ideal, atom-efficient method to prepare carboxylic amides from easily available olefins, CO, and amines. So far, aliphatic amines are not suitable for these transformations. Here, we present a ligand- and additive-free Rh(I) catalyst as solution to this problem. Various amides are obtained in good yields and excellent regioselectivities. Notably, chemoselective

The present invention relates to A process for enzymatic synthesis of amides of formula (III) from amines of formula (I) and compounds of formula (II), characterized in that the lipase is immobilized on a rotary bed reactor or on a spin-fixed-bed reactor and a Dean-Stark apparatus is used for dehydration.

Come together, right now: Acyltrifluoroborates and O‐benzoyl hydroxylamines come together to form amides in water (see scheme). The ligations are complete within minutes at room temperature and do not require any reagents or catalysts. The reaction has a broad substrate scope and tolerates unprotected functional groups.
