2. Alkene substitution
2.1 Historic first step: ethylene
In 1828, Zeise obtained a platinum compound that was formulated in a dualistic form for a very long time due to the lack of structural information: PtCl 2 · KCl · C 2 H 4 . It took around 130 years for its structure to be established by X-ray diffraction. It is a potassium salt of the complex anion [PtCl 3 (C 2 H 4 )] - in which the four PtCl 3 atoms are in the same plane perpendicular to the...
