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

Abstract

Flash Vacuum Pyrolysis of (a-phenylethyl) and (P-phenylethy1)-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 LY and p carbons of the ethyl group in the FVP of N-alkyl pyrazoles and (p-haloethyl) pyrazoles.
