X‐ray crystallographic evidence shows that nucleophilic substitution reactions of two different types of cyclophosphazene derivatives with relatively rigid nine‐membered ansa rings leads to the first demonstration of retention of configuration in these molecular systems. X‐ray crystallography provides evidence of retention of configuration in nucleophilic substitution reactions of two different types of cyclophosphazene derivatives (see example) containing nine‐membered ansa rings that are relatively rigid, which suggests that this mechanism may be less rare than considered previously.
