Sterically hindered, stable 3-thiophenecarbonitrile oxides containing electron-accepting groups (SO2R, Br) in the 2- or 4-position are converted to substituted 4,5-dithienylfuroxanes when boiled in benzene or toluene, whereas trialkyl-substituted 3-thiophenecarbonitrile oxides isomerize quantitatively to the corresponding isocyanates.
