Abstract: 4-(Dimethylaminomethylene)-5-oxo-2-furfurylidenedimethyliminium perchlorate (a new vinamidinium system with incorporated 2(3H)-furanone ring) was prepared by reaction of 2(5H)- resp. 2(3H)-furanone with the Vilsmeier type reagent; its reactions with C-nucleophiles were studied. Some spectral properties of the prepared compounds are discussed.
