A simple method for the synthesis of 2-pyrazolines is described which occurs on silica surface undersolvent-freeconditions within 110-180 sec using microwaveirradiation. 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.
