Notes:
(1)The rates of reaction of 2, 4-dinitrofluorobenzene with morpholine have been measured in benzene solution, with and without the addition of pyridine or 1, 4-diaza-bicyclo[2.2.2]octane (DABCO) as catalysts.(2)The reaction is catalyzed by morpholine, pyridine and DABCO; the rate laws as functions of these bases are expressed by equations (2)-(4).(3)The reaction is considerably more sensitive to pyridine and DABCO catalysis than that of 2, 4-dinitrofluorobenzene with the sterically identical, but more basic piperidine. These findings confirm a previously found trend of greater sensitivity to base catalysis with decreasing base strength of the reacting amine.
