Insertion reactions of hexafluoroacetone with tricarbonyl(diene)iron and π-cyclopentadienyl(diene)rhodium complexes
Abstract
The reaction of hexafluoroacetone (HFA) with various tricarbonyl-(1,3-diene)iron complexes affords adducts containing one or two molecules of HFA, the latter adducts being transformed on heating into products, in which HFA has formally inserted into carbon–hydrogen bonds; analogous reactions with cyclopentadienylrhodium complexes lead to insertion of one or two HFA molecules into cyclopentadienyl carbon–hydrogen bonds.
