Chlorotris(triphenylphosphine)cobalt(I) (‌4‌) is often used as the starting material in the synthesis of various cobalt(I) complexes. It has been shown that, like dicarbonyl(η5-cyclopentadienyl)cobalt(I), it reacts with benzocyclobutenedione and 3,4-dimethylcyclobutenedione to furnish the corresponding phthaloyl- and maleoylcobalt complexes, ultimately leading to the formation of the naphtho- and benzoquinones (see Sections ‌1.4.1.4‌ and ‌1.4.1.11‌).[‌141‌] In addition, complex ‌4‌ is a novel mediator for the conversion of benzylic bromides into aromatic aldehydes.[‌216‌]
