PYRAZOLINES: PART II
Product analysis has been carried out on the pyrolysis reaction in the liquid and vapor phase of 4- and 5-methyl-3-carbomethoxy-Δ 2 -pyrazolines and 3-methyl-3-carbomethoxy-Δ 1 -pyrazoline. The proportion of cyclopropane product was found to be greater than earlier reports had indicated and was high...
