Abstract
C-5-unsubstituted 5-aminorhodanines 1 are converted to 5-hydroximino-r hodanines 2 with NaNO2/HCl, nitrosyl- and nitronium-tetrafluoroborate. With HNO3, 5-hydroximinothiazolidine-2,4-diones 3 arise. Under drasti c conditions 5-arallcyliden-3-aminorhodanines 7 are desulfurized oxida tively in 2-position by HNO2.
