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.
描述了制备 4,5-二亚氨基-[1,3]二硫环和 2,3-二亚氨基-[1,4]二硫环的工艺。这些工艺包括将草酰胺转化为二硫代草酰胺,然后将二硫代草酰胺转化为 4,5-二亚氨基-[1,3]二硫环戊烷或 2,3-二亚氨基-[1,4]二噻烷。
