Jm. Mcgill et Ms. Miller, THE FORMATION OF 3-CHLORO-1,2,5-THIADIAZOLES FROM ALPHA-OXIMIDONITRILES - OPTIMIZATION AND MECHANISTIC INSIGHTS, Heterocycles, 48(10), 1998, pp. 2111-2123
The optimized formation of substituted 3-chloro-1,2,5-thiadiazoles (2)
and (3) from the alpha-oximidonitrile (4) is described. New mechanist
ic insight into the formation of 3-chloro-1,2,5-thiadiazoles comes fro
m the identification of a reaction intermediate in the thiadiazole rin
g-forming reaction.
