complex f(Ph3P)2PdC03] tended to decompose in solution as it was formed, so with [(Ph3P)2PdCl2], the suspension was stirred only for about 15 min. However, the product obtained was always impure.Adduct of Carbon Disulfide with [(Ph3P)2Pt02]. Carbon disulfide was added dropwise to a solution or suspension of f(Ph3P)2-Pt02] (0.75 g) in ice-cold benzene-ether (5 ml/5 ml) until no further reaction was observed (usually 3-4 drops). The orange crystals formed were filtered off rapidly, washed with ice-cold ether, and dried in vacuo.The compound tended to decompose to the dithiocarbonate analog in solution but was quite stable when dry; yield, 0.75 g (about 90%). A similar procedure with [(Ph3P)2-Pd02] gave the dithiocarbonate directly, and oxygen was evolved on addition of CS2.
