Application
Chloro(dimethylsulfide)gold(I) serves as a versatile precursor in the synthesis of various gold(I) catalysts, offering significant utility in organic synthesis. This compound is particularly effective in catalyzing the intermolecular [2+2] cycloaddition of terminal alkynes with substituted alkenes to form substituted cyclobutenes under mild conditions. Additionally, it is used in the synthesis of other important gold complexes, including chloro(trimesitylphosphine)gold(I), gold(I) N-heterocyclic carbene (NHC) complexes, bis(carbene)gold(I) complexes of ferrocenyl compounds, and gold(I) acetylide complexes. Furthermore, it acts as a foundational gold(I) precursor for developing more advanced gold catalysts, which are crucial in converting propargyl sulfoxides into α-thioenones.
