Reaction of 4-X-benzyltriphenylphosphonium halides with 2-furaldehyde and subsequent Vilsmeier formylation gave 5-(4-X-styryl)-2-furaldehydes ( X = H, Cl, Br, CN, NO2, CH3, and COOCH3). The UV, IR and 1H-NMR spectra of the prepared substances are discussed and it is demonstrated that the compounds are (E) isomers. The UV spectra of 5-styryl-2-furaldehyde have been compared with those of its benzene analogue.
