made of the attack of amines on platinumcomplexes containing ethene derivatives. When 2-ammonioethanide compounds (H3NCHRCHR′–Pt) are formed, the direction of attack is determined by electronic rather than steric effects unless the latter are very large. Reactions are not complete, and equilibrium constants show that steric factors tend to prevent the formation of the 2-ammonioethanide compounds. The
