Abstract

... VOL. ... d,g. The usual Hammett plot of equilibrium constant (K = [1,5-isomer]/ [l,3-isomer]) as a function of o, for the substituents (H, OMe, CN) on the 3(5)-aryl group reveals a linear relation- ship with slope p = +0.78 (correlation ... Yield from the pyrazoline was 52% (bp 4OoC/2.6 Torr ...
