1. A process for producing preparations comprising one or more mononuclear platinum complex compounds of formula (X)
[olefin1]x[olefin2]y Pt2+ Hal−2, where
Hal=F, Cl, Br or I,x=1 or 2,y=0 or 1,olefin1=a compound comprising at least one olefinic unsaturation and fewer than two oxygen atoms,olefin2=a compound comprising an olefinic unsaturation and fewer than two oxygen atoms,with the proviso that when olefin1 comprises at least two olefinic unsaturations, x=1, and x+y=1, and when olefin1 comprises only one olefinic unsaturation, x+y=2,one or more compounds comprising carbon atoms, hydrogen atoms and at least two oxygen atoms as compound(s) from compound class II,and one or more olefinically unsaturated compound(s) selected from olefin1 and olefin2 as compound(s) from compound class III, said process comprising:contacting at least one compound from each of compound classes II and III with one or more dinuclear platinum (II) compound(s) as compound(s) from compound class I, wherein said contacting comprises, in a first step, preparing a mixture by adding together at least two compounds selected from two different compound classes, and, in a second step, admixing the mixture obtained in the first step with one or more compounds of the absent compound class. |
