摘要：

Fe(III)-catecholato complexes with the hydrotris(pyrazolyl)borate ligands (Tp(R); R denotes substituents of the 3- and 5-positions of the pyrazolyl rings) are synthesized as structural and functional models for catechol dioxygenase enzymes. Coordination geometry of the Fe centers depends on the steric hindrance of the Tp(R) ligands. O-2 treatment of Tp(Pri2)Fe(III)(DBC) (DBCH2 = 3,5-di-tert-butylcatechol) affords as major products those derived from extradiol cleavage of the catechol, although a highly hindered Tp(R) ligand complex, Tp(But,Pri)Fe(III)(DBC), is relatively inert toward O-2.
