An eco-friendly and simple procedure for the reaction of 2-(1-(benzofuran-2-yl)ethylidene)hydrazinecarbothioamide with arylidenemalononitriles and hydrazonoyl halides catalyzed by using sterically hindered organic base, 1,4-diazabicyclo[2.2.2]octane (DABCO) was described. This new protocol has the advantage of good yields and short reaction times. The structure of the newly synthesized compounds was elucidated via elemental analyses and spectral data.
