资源简介：
A set of substituted tris(pyrazolyl)phosphine oxides
(OP(pzx)3) has been prepared in high yield and
applied
as neutral scorpion-type ligands. The P apex provides a convenient
spectroscopic handle. Substitution at the 3-position of the pyrazolyl
ring influences the steric demands of the ligand, while substitution
at the 5-position enhances the stability. Copper(I) acetonitrile complexes
of the OP(pzx)3 ligands were prepared and tested
in ligand exchange reactions with PPh3 and CO. The ν(CO)
values of the carbonyl complexes demonstrate the electron-withdrawing
properties of the ligands. These observations show that OP(pzx)3 ligands are an interesting extension of the
widely used scorpion-type ligands.
