Description Application Chloro(dimethylsulfide)gold(I) can be used to synthesize a gold(I)-catalyst that can effectively catalyze intermolecular [2+2] cycloaddition of terminal alkynes with substituted alkenes to form substituted cyclobutenes under mild reaction conditions. It can also be used to synthesize: • chloro(trimesitylphosphine)gold(I) • gold(I) N-heterocyclic carbene (NHC) complexes • bis(carbene)gold(I) complex of ferrocenyl complexes • gold(I) acetylide complexes Packaging 1 g in glass bottle 250 mg in glass bottle
