Chloro(triphenylphosphine)gold(I) is a common reagent in gold chemistry. It catalyzes certain rearrangement reactions in organic synthesis. It is also used to prepare 1-methylthyminato-N3-triphenylphosphinegold(I) by reacting with 1-methylthymine. It acts as a precursor for the synthesis of gold(I) and gold(III) organometallic compounds.
