Microwave-assisted solvent-free synthesis of new (D-π-A) chromogenes, 2-ferrocenyl-1,1-dicyanobuta-1,3-diene derivatives (II), have been accomplished through the condensation of 2-(1-ferrocenylethylidene)malononitrile (I) and aromatic aldehydes with sarcosine as the catalyst and identified by 1H NMR, 13C NMR and FT-IR. Compound IId was determined by X-ray crystallography (CIF file CCDC no. 1056735). The crystal belongs to monoclinic, space group P21/c. The possible reaction mechanism has been studied.
