Hydrazonoyl halides have been caused to react with each of ethyl 4-(2H-benzo[3,4-d]1,3-dioxolen-5-yl)-6-methyl-2-methylthio-3,4- dihydropyrimidin-5-carboxylate, potassium thiocyanate (or thiourea), potassium selenocyanate, and alkyl carbodithioate in the presence of triethylamine to give 4,3-dihydro-1,2,4-triazolino[4,3-a]pyrimidine, 1,3,4-thiadiazoline, 1,2,4-selenadiazoline, and unsymmetrical azine derivatives in good yields. Structures of the new compounds were elucidated on the basis of elemental analyses, spectral data, and alternative methods of synthesis whenever possible.
