REACTIONS OF ARYL AZIDES WITH COBALTADITHIOLENES - SUBSTITUTION-REACTIONS VIA NITRENE

Two types of substitution reactions occur between arylnitrene from aryl azides (1) and a cobaltadithiolene, (eta(5)-cyclopentadienyl)(1,2-dicyano-1,2-ethenedithiolato)cobalt-(III): 1) replacements of S by arylimino groups and 2) replacements of S-CX=CX moiety of a cobaltadithiolene by a biradical form of nitrene to give (eta 5-cyclopentadienyl)(2-imino-kappa N-arene-1-thiolato-kappa S)cobalt(III) (5). The reaction of 1 with a cluster compound [Cp(4)Co(4)S(6)] gives also 5.
