Preparation of Metal Alkene Complexes

A number of synthetic methods are useful for preparing metal alkene complexes. A few of the more general ones will be described here, but the suggested readings given at the end of the chapter should be consulted for more details. 

This method is the one of those that can be used to prepare the ethylene complex known as Zeise s salt, K[Pt(C2H4)Cl3]. Actually, the dimer [Pt(C2H4)Cl2]2 is obtained first and the potassium salt is obtained by treating a concentrated solution of the dimer with KC1. 

Other metal complexes containing several types of unsaturated compounds as ligands can be prepared by similar reactions.
