1390-1394Reaction of monophosphinite ligand, 2-(diphenylphosphinoxy)
naphthyl, C10H7PPh2 (1) with elemental sulphur
or selenium gives the corresponding sulphide C10H7OP(S)Ph2
(2) or
selenide C10H7OP(Se)ph2
(3) derivatives. Reaction of 1 with [CpRu(PPh3)2Cl]
gives monosubstituted complex, [CpRu(C10H7OPPh2)(PPh3)C1]
(4) as well as the disubstituted
complex. [CpRu(C10H7PPh2)2Cl]
(5) depending upon the reaction conditions. Treatment of 1 with [Rh(CO)2Cl]2
affords a trans-complex, [Rh(CO)(C10H7PPh2Cl]
(6). Reaction of 1 with [Pd(COD)Cl2] results in the formation
of an unexpected chlorobridged dipalladium complex: [Pd (PPh2O)( PPh2OH)(μ-Cl)]2 (7), whereas similar reaction
with [pt(COD)Cl2] gives cis-[Pt(C10H7PPh2)2Cl2]
(8) in good yield
