Sz. Wu et al., SYNTHESIS OF SOME FERROCENYL SUBSTITUTED 1,2,4-S-TRIAZOLO-[3,4-B]-1,3,4-THIADIAZOLES, Synthesis and reactivity in inorganic and metal-organic chemistry, 24(8), 1994, pp. 1359-1364
Six new rrocenyl-1,2,4-triazolo-[3,4-b]-1,3,4-thiadiazoles have been s
ynthesized by the condensation of 3-substituted-4-amino-5-mercapto-1,2
,4-s-triazoles with ferrocene carboxylic acid in the presence of phosp
horous oxychloride. These compounds were characterized by elemental an
alyses, IR, UV and H-1 NMR spectra.
