Abstract
A large number of aminophosphines were prepared to study the kinetic processes. It could be shown that at room temperature there is rapid nitrogen-inversion but slow phosphorous-inversion. At higher temperatures ( + 80 °C), a rapid chlorine-exchange takes place with inversion of configuration at phosphorous. At low temperatures ( — 80 °C), rotation around the N-P-bond was slow. A dependence of the barrier of rotation on the size of the substituents could be recognized. It is possible that pπ-dπ-bonding is partially responsible for the relatively high barrier of rotation compared with derivatives of ethane and hydrazine.Keywords
