Cyclopropane derivatives were prepared by the reaction of diazocompounds and alkene without catalyst under microwave irradiation, which demonstrated that it is an efficient method in organic chemistry. Compared with traditional metal catalyzed cyclopropane, this method is convenient and less harmful to environment. A second-order process was involved in the cyclopropanation as shown by the kinetic study.
