Abstract
A process is provided for preparing cis-Pt(NH.sub.3).sub.2 Cl.sub.2 and intermediates. As a step in the process the intermediate cis-Pt(NH.sub.3).sub.2 I.sub.2 is prepared from K.sub.2 PtI.sub.4 by adding NH.sub.4 OH under controlled conditions of temperature and pH. The cis-Pt(NH.sub.3).sub.2 Cl.sub.2 is provided in high yield and purity.
