Oxidative Addition of Glycosylbromides to <i>trans-</i>Ir(PMe₃)₂(CO)Cl

trans-Ir(PMe3)2(CO)Cl reacts with acetobromo-α-d-glucose in the presence of AIBN to give a 1.3:1 ratio of the retentive and invertive oxidative addition products, each of which were characterized by crystallography. Reaction with α-d-glucopyranosyl bromide tetrabenzoate gave a 2:1 α:β ratio, while acetobromo-α-d-mannose gave a 5:1 ratio of retentive to invertive products.
