The effects of ring substituents and leaving groups on the kinetics of SNAr reactions of 1-halogeno- and 1-phenoxy-nitrobenzenes with aliphatic amines in acetonitrile

Crampton, Michael R.,Emokpae, Thomas A.,Isanbor, Chukwuemeka

, p. 1378 - 1383 (2008/09/18)

Rate constants are reported for the reactions of a series of 1-chloro-, 1-fluoro- and 1-phenoxy-nitrobenzenes activated by CF3 or CN groups or by ring-nitrogen with n-butylamine, pyrrolidine or piperidine in acetonitrile. The results are compar
