note

In one experiment when a larger amount of potassium tert-butoxide was used, the 1H pyrazoline i was isolated in essentially quantitative yield. This compound is presumably formed by isomerization of the initially formed pyrazoline 16. (formula presented)

note
-
Although the ratio of products is dependent on the relative energies of the transition states leading to them, one can often estimate the differences by examining the energies of the products. Calculations (PM3) of close models (with hydrogen in place of benzyl) indicate that the two products 18 and 19 are essentially equivalent in energy (19-H is favored by 0.28 kcal/mol over 18-H) while the two pyrazolines (16 and epi-16. the other cis diastereomer) are very different in energy with 16 being favored by 2.6 kcal/mol.
