- Abstract
A mechanism is proposed for the substitution of the first halogen atom in N-pentafluorophenylcarbonimidoyl dihalides (ArFN=CX2, X = Cl, Br) by aliphatic amines and includes a tetrahedral intermediate (TE). In the case of the reactions of primary and secondary amines the rate-limiting stage is the formation of the intermediate, and in the case of tertiary amines it is stereomutation of the intermediate (TE) to the thermodynamically more stable configuration (TZ) In the case of all the amines the final product (the Z isomer) is formed from the configuration (TZ).
