Abstract
The reactions of a series of substituted benzohydrazonoyl halides with cyclic
secondary amines in benzene as solvent are investigated. The rate equations
for these reactions were complex and the derived rate data are reported. The
element effect data showed that the fluoro compounds only reacted when a
second amine molecule was available to assist the reaction, whereas the chloro
and bromo compounds reacted by reactions which were both first order and
second order in amine
(k′′Br :
k′′Cl =
9·5 : 1 and
k′′′Br
:k′′′Cl :
k′′′F = 4·7 : 1 :
0·65). The mechanism of these reactions is discussed.
