Popis: The phosphazene super bases BTPP 5 , P-2- t Bu 6 , and P-4- t Bu 7 mediate the rearrangement of unactivated N -alkyl- O -benzoyl hydroxamic acid derivatives 8 , 11a – f , 13 and 16 to give 2-benzoyloxy amides 9 , 12a – f , 14 and 17 . The rate of reaction was found to be dependant upon the steric nature of the N -alkyl substituent.
