Abstract (en)
[origin: WO02053613A1] The invention concerns the use of a compound comprising a nitrogenous heterocyclic group with five cyclic members including at least two nitrogen atoms, one of the nitrogen atoms bearing a hydrogen atom to promote the opening/closing reaction of uretidione cycles in the presence of a nucleophile compound provided that, when the nitrogenous heterocyclic group is imidazole, the opening/closing reaction is not the closing reaction of the uretidione cycle in the presence of a quaternary ammonium salt.
