An efficient and greener approach to the synthesis of 3,5dicyanopyridin21Hone derivatives in aqueous media under microwave irradiation conditions

A facile and greener synthesis of a series of 3,5dicyanopyridin21Hone derivatives was accomplished viathe onepot reaction of aldehyde, malononitrile and sodium hydroxide in aqueous media under microwave irradiation. This method had several advantages such as shorter route and time, lower cost, reduced environmental impact.
