-bromo/nitropyrazoles in water in the presence of bases were accompanied by thiirane–thietane rearrangement to afford 4-bromo

dimethyl 2-bromo-1-(thietan-3-yl)-1H-imidazole-4,5-dicarboxylate which was oxidized to dimethyl 2-bromo-1

containing a thietane ring with yields of 76 - 93%. Interaction of these acids with bases (sodium hydroxide

The reaction of 8-bromo-substituted 3-methyl-7-(thietan-3-yl)-3,7-dihydro-1H-purine-2,6-diones

A series of 8-amino-substituted 1-butyl-3-methylxanthines containing a thietane ring were obtained

5-Alkoxy- and 5-amino-substituted 3-bromo-4-nitro-1-(thietan-3-yl)-1H-pyrazoles were synthesized

1-Alkyl-8-bromo-3-methyl-7-(1,1-dioxo-1λ6-thietan-3-yl)-3,7-dihydro-1H-purine-2,6-diones reacted

-aryloxy- and 5-phenylsulfanyl-3-bromo-1,2,4-triazoles containing thietane or thietane oxide rings. The 3

Thietane-containing 4-(2-oxo-2-phenylethyl)-1H-1,2,4-triazol-4-ium bromides were synthesized

5-Amino-substituted 3-bromo-1-(thietan-3-yl)-4-nitro-1H-pyrazoles were synthesized by reacting 3
