Abstract

The structures of α,α-bis(furfurylideneimino)silvan (“furfuramide” or N,N'-difurfurylidene-2-furanmethanediamine) and the product of its thermal cyclization 2,4,5-tris (α-furyl)-2-imidazoline (“furfurine”) were confirmed by comparison of the IR, UV, 1H and 13C NMR, and mass spectra. It is shown that acetylation of the latter with acetic anhydride in the case of heating of the reagents without a solvent or in pyridine takes place with opening of the imidazoline ring and leads to the formation of 1,2-bis(α-furyl)-1-acetamido-2-(α-furoylamido)ethane.
