Abstract

The formation of tricarbonyl(tetramethylcyclobutadiene)cobalt hexafluorophosphate and its conversion into the neutral complexes [{Co(CO)2(C4Me4)}2] and [Co(CO)2(C4Me4)I] are described. Reaction of the latter with arenes in the presence of aluminium chloride provides a general route to the cations [Co(C4Me4)(arene)]+ of which seven new examples are described. Some carbonyl substitutions of the cation [Co(CO)3(C4Me4)]+ are also reported.
