The observation of an enantiospecific C-H bond activation, followed by iodi
nation at an allylic position of a coordinated 1,5-COD ligand in a chiral I
r-(I) complex upon addition of I-2 in CH2Cl2 is reported. The same reaction
carried out in THF affords an allylic eta(3),eta(2)-COD derivative. Both r
eaction products were characterized by X-ray diffraction.
