Abstract
NEW MATERIAL:4H-indenothiadiazole derivative of formula I (R1 is H, halogen, nitro, lower alkyl, lower alkoxy; R2 is halogen, nitro, lower alkyl, lower alkoxy).
EXAMPLE: 5,8-Dimethyl-4-oxo-4H-indeno[1,2-c]-1,2,5-thiadiazole.
USE: Fungicide. Intermediate of pharmaceuticals.
PROCESS: The compound I is prepared by reacting a compound II (X is methylene, carbonyl) with nitrogen tetrasulfide in an inert solvent (e.g. benzene, toluene, xylene, monochlorobenzene, etc.) for several to several ten hours, pref. with heating.
