Abstract
C-acyl-N-(3-phenyl-5-pyrazolyl)hydrazonoyl chlorides 1a,b react with potassium thiocyanate and potassium selenocyanate to give 5-acyl-2,3-dihydro-2-imino-3-(3′-phenyl)pyrazol-5′-yl)-1,3,4-thiadiazoles 2a,b and 5-acetyl-2,3-dihydro;-2-imino-3-(3′-phenyl)pyrazol-5′-yl)-1,3,4-selenadiazole 10a,b. Also, 2-[mercapto-(methylthio)methylene]indan-1,3-dione 16 reacts with hydrazonoyl halides 15 and 22–25 to afford 2,3-dihydro-1,3,4-thiadiazoles 19 and 26–29, respectively. Structures of the newly synthesized compounds are elucidated on the basis of spectral data, chemical transformations, and alternative synthesis methods. © 2001 John Wiley & Sons, Inc.
