Oxotrichlorobis(triphenylphosphine)rhenium(V)

Oxotrichlorobis(triphenylphosphine)rhenium(V) is the chemical compound with the formula ReOCl3(PPh3)2.

This yellow, air-stable solid is a precursor to a variety of other rhenium complexes.

[1] In this diamagnetic compound, Re has an octahedral coordination environment with one oxo, three chloro and two mutually trans triphenylphosphine ligands.

The required perrhenic acid solution can be prepared in situ from rhenium(VII) oxide.

[2] ReOCl3(PPh3)2 catalyzes the selective oxidation of secondary alcohols by DMSO, producing the corresponding ketals.
