Chloro(triphenylphosphine)gold(I) is the coordination complex with the formula (Ph3P)AuCl (Ph = phenyl). This colorless solid is the complex of triphenylphosphine and gold(I) chloride.
The complex is prepared by reducing chloroauric acid with triphenylphosphine in 95% ethanol:[1]
The complex adopts a linear coordination geometry, which is typical of most gold(I) compounds.[2][3]
It is a common reagent in gold chemistry. Many related gold complexes (often incorrectly called salts) can be prepared including the trifluoromethanesulfonate and the nitrate.[4]
Triphenylphosphine gold triflate (Ph3PAuOTf) catalyzes certain rearrangement reactions in organic synthesis.
