Unusual reactivity of the bis(pyrazolyl)borate Chelate: B-H for B-X (X = F, Cl, OH) Substitution in Complexes of Ruthenium

Page, Michael; Messerle, Barbara Ann; Wagler, Jorg


Reaction of the complex [RuTp(Bp)PPh3] (6, where Tp = tris(pyrazolyl)borate and Bp = bis(pyrazolyl)borate) with AgBF4, AgOTf,and SOCl2 was observed to yield the highly unusual B-F- and B-OH-containing compounds [RuTp(BpF2)PPh3] (7), [RuTp(BpOH)PPh3]OTf (9), and [RuTp-(BpOH) PPh3]Cl (10), respectively, via substitution of the Bp boron-hydride groups. The complexes 7 and 9 were structurally characterized by X-ray crystallography. Formation of the B-F product 7 represents a rare example of BF4...[Show more]
