The reaction of diethyl bromomalonate (1) or diethyl diazomalonate (6) with benzoyl isothiocyanate (2) proceeds via the carbene intermediates 4,7 or 12 to afford the 1,3-dithiole 5, the Δ2-oxazoline 8 or the 1,3-oxathioles 9 depending upon the catalyst employed.In contrast, the bis(ethoxycarbonyl)methylpyridinium bromides 14 upon treatment with benzoyl isocyanates 15 in pyridine give rise to vinylene dipyridinium dibromides 18.- Keywords: Heterocyclizations; 1H-NMR-Spectroscopy; Iso(thio)cyanates; Malonates
