The transamidation between formamide and various amines proceeds under heating, without any catalyst nor solvent, providing thus green and neutral conditions for the formylation of primary and secondary amines. The resulting amide product can be directly transformed, in a one pot sequence, into monomethylamine.
Pass the salt please! A simple fluorous salt of 4‐N,N‐dimethylaminopyridine (C7F15CO2H⋅DMAP) that acts as an effective recyclable organocatalyst for esterification under solvent‐ and base‐free conditions is reported. This catalyst is readily accessible, easy to handle and to recover, and constitutes an attractive alternative for cleaner and safer acylation reactions (see scheme).
