Abstract (en)

[origin: WO0236585A2] Processes for the preparation of 4,5-bisimino-[1,3]dithiolanes and 2,3-bisimino-[1,4]dithianes are described. The processes involve conversion of an oxalamide to a dithiooxalamide, followed by conversion of the dithiooxalamide to either a 4,5-bisimino-[1,3]dithiolane or a 2,3-bisimino-[1,4]dithiane.
