Reactions of Aryl Azides with Cobaltadithiolenes. Substitution Reactions via Nitrene

Article abstract of DOI:10.1246/cl.1994.1165

Two types of substitution reactions occur between arylnitrene from aryl azides (1) and a cobaltadithiolene, (η⁵-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 (η⁵-cyclopentadienyl)(2-imino-κN-arene-1-thiolato-κS)cobalt(III) (5).The reaction of 1 with a cluster compound gives also 5.
