Generation and reactivity of the dehydrotropylium-Co(2)(CO)(6) ion
Dehydrotropylium-Co(2)(CO)(6) ion (2) has been generated by the Lewis acid mediated ionization of alcohol (3); it is attacked by relatively strong nucleophiles (N > 1), but undergoes a radical homocoupling in the presence of weak nucleophiles (N < 1).
