Beschreibung

Anwendung

2,2′-Thiodiethanol is used in the preparation of a wide range of gold complexes, which include Au(I) based catalysts such as chloro(triphenylphosphine)gold(I) [Au(PPh₃)Cl], chloro(dimethyl sulfide)gold(I) [Au(SMe₂)Cl] and chloro[1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene]gold(I) [IPrAuCl]. It can also be used to build calixarene frameworks.
