Kinetics of gas‐phase thermal elimination of (α‐phenylethyl) and (β‐phenylethyl)‐pyrazole

Abstract Flash Vaccum Pyrolysis of (α‐phenylethyl) and (β‐phenylethyl)‐pyrazole were studied. Pyrazole and Styrene were found as only products of both reactions. The kinetic parameters obtained reinforce the results previously found about the poor influence of the substitutents on the α and β carbons of the ethyl group in the FVP of N ‐alkyl pyrazoles and (β‐haloethyl) pyrazoles.
