Atom transfer reactions involving the metal-centred radical [(η5-C5H5)Cr(CO)3]·
Abstract
The metal-centred radical [(η5-C5H5)Cr(CO)3]· abstracts the halogen atoms from a number of alkyl, allyl and benzyl halides to form the halochromium compounds [(η5-C5H5)Cr(CO)3X](X = Br, I) and the corresponding carbon-centred radicals; the latter subsequently undergo a wide variety of coupling, atom abstraction and atom donation reactions.
