Resumen:
In this article we report on the
thermal reactions of 3-methyl-1(2),4,5,6-tetrahydrocyclopenta[c] pyrazole (1) and
1,10,10-trimethyl-5-trifluoromethyl3,4-diazatricyclo[5.2.1.02,6]deca-2(6),5(4)-diene
(2) under FVP conditions. While in
the first case all products arise from a nitrogen extrusion reaction, in the
second one, ring isomerization is the principal reaction. The choice of these
substrates has allowed to continue the research on the influence of
substituents on the kinetics of the thermal reactions of pyrazoles.Kinetic parameters for FVP reactions
of 1 and of
3(5)-methyl, 5(3)-phenyl-pyrazole (3)
are also reported.
