A process is provided for the synthesis of a cyclic imide. A primary amine and a diol compound are contacted in the presence of a Ruthenium (II) complex. The Ruthenium (II) catalyst includes at least one of an alicyclic ligand, an aromatic ligand, an arylalicyclic ligand, an arylaliphatic ligand and a phosphine ligand.
LiNTf2 in the reaction of lactones with amines is able to activate cyclic esters towards ring opening, thus leading to clean open-chain amides under mild conditions and using a stoichiometric amount of amine. The generality of the method was demonstrated by a range of selected lactones and amines.

There′s something imide so strong: Cyclicimides were synthesized fromsimplediols with primary amines in a single step using an in‐situ‐generated ruthenium catalytic system. The atom‐economical and operatively simple syntheses of succinimides, phthalimides, and glutarimides, which are important building blocks in natural products and drugs, was also demonstrated.
