Abstract

The poly(pyrazol-1-yl)borate complexes PdMe{(pz) 3BR-N,N′}(PPh 3) (R = H, pz) are formed on the reaction of [PdMe(SME 2)(μ-I)] 2 with K[(pz) 3BR] in the presence of PPh 3 and TlPF 6, and the phenylpalladium(II) analogues are formed directly from PdIPh(tmeda) (tmeda = N,N,N′,N′-tetramethylethylenediamine) and K[(pz) 3BR] in the presence of PPh 3. X-ray diffraction studies of PdR{(pz) 4B-N,N′}(PPh 3) (R = Me, Ph) and PdPh{(pz) 3BH-N,N′}(PPh 3) reveal square planar geometry for palladium with the poly(pyrazol-1-yl)borate ligands in bidentate mode. The structure of Pd(η 3-C 3H 5)[lcub](pz) 3BH-N,N′[rcub] has also been determined, and it contains a bidentate tris(pyrazol-1-yl)borate group with the η 3-allyl group forming a dihedral angle of 125.5(2.1)° with the PdN 2 plane. In both PdPh{(pz) 3BH-N,N′}(PPh 3 and Pd(η 3-C 3H 5){(pz) 3BH-N,N′} the uncoordinated pyrazole group lies above the coordination plane. © 1995.
