N-heterocyclic carbene (NHC)-catalyzed intramolecular cyclization of acrylamides that contain a 2-fluorophenyl group on the nitrogen through a CSN Ar reaction. By using this catalytic method, it is possible to synthesize an array of quinolin-2-one derivatives, which are common structural motifs in pharmaceuticals and organic materials. DFT calculations unambiguously revealed that this reaction proceeds through

the N,N′-diarylformamidine complexes of formula fac-[Mn(RN═C(H)NHR)(bipy)(CO)3]+ (1a, R = phenyl; 1b, R = 4-dimethylaminophenyl) produces, upon deprotonation, either the monodentate formamidinatecomplex fac-[Mn(PhN═C(H)NPh)(bipy)(CO)3] (2a) or metallacylic complex 3b, which features a carbamoyl residue arising from nucleophilic attack to a vicinal carbonyl ligand. Complexes type 3 are also formed when
