Abstract
Synthesis of 1,2,5,6-Tetrahydropyrimidines On a Base Induced Ring Enlargement of 1H-3-Pyrazolines 5,5-Bis(trifluoromethyl)-2-[2,2,2-trifluoro-1-(trifluoromethyl)ethyl]-1H-3-pyrazolines 1 on treatment with bases are transformed into 1,2,5,6-tetrahydro-2,2,6,6-tetrakis(trifluoromethyl)pyrimidines 2. A reaction mechanism is proposed.
