The reaction of C5H5Co(CNMe)(PMe3)(2) with C3H5NCE and n-C3H7NCE (E = O, S) leads to the formation of cobaltaheterocycles 4–7 which contain a CoCNC framework. The complexes 6 and 7 with an exocyclic CS group are formed via the cobaltathietanes 8 and 9 as intermediates. Protonation of 4, 5, 7 and 8 with HBF4 occurs at the exocyclic CNMe unit and gives the cationic metallaheterocycles 10, 11, 15 and
