An artificial receptor that is complementary to the proposed trigonal-bipyramidal intermediate for phosphoryl-transfer reactions has been designed. Kinetic measurements with P-31 NMR methods show that the receptor causes up to a 10-fold accleration in the aminolysis of phosphorodiamidic chloride derivatives, proceeding via an associative mechanism.
