Bis dimethylsulfoxide methylchloroplatinum II

This method has been reported by Eaborn et al.8 The preparation of this compound requires about 36 h. 

Dimethylsulfoxide is purified by filtration through a 2 x 25 cm chromatographic column filled with alumina (activated grade I, neutral, 150 mesh), under a nitrogen atmosphere. This procedure of purification of the solvent is crucial to obtain the indicated yield, since on use of distilled or commercially available anhydrous dimethylsulfoxide, extensive decomposition takes place.
