Reactions of allylpalladium(ii) complexes with free radicals

Abstract

Allylpalladium(II) compounds react readily in benzene with free phenyl and trityl radicals, generated from the thermal decomposition of phenylazotriphenylmethane, and with free cyclohexyl radicals, generated from the photolysis of (cyclohexyl)(pyridine)cobaloxime; the reactions appear to involve initial attack of the radicals at palladium, followed by secondary processes which convert the coordinated allyl ligands preferentially to terminal rather than internal alkenes.
