✦ Synopsis

A simple method for the synthesis of 2-pyrazolines is described which occurs on silica surface under solvent-free conditions within 110-180 sec using microwave irradiation. The results obtained indicate that the use of silica gel as a support in pyrazoline formation reactions can have a profound effect on reaction rates and yields and cause cleaner reaction conditions.
