- Five-Membered Chalcogen Heterocycles as Synthons for Heterodienes: Synthesis of Δ4-1,4,2λ5-Thiaza- and Δ4-1,4,2λ5-Selenazaphospholines
-
Syntheses of 3,3-bis(trifluoromethyl)-3H-1,2,4-thiaselenazoles 3, -3H-1,2,4-thiatellurazoles 4, and -3H-1,2,4-diselenazoles 13 are described.These new classes of compounds can be used as synthons for 1-thia-3-aza-1,3-butadienes and 1-selena-3-aza-1,3-buta
