Abstract
Novel phosphorus compounds bearing fluorine substituted 1,2,4-triazolo[3,2-c][1,2,4]triazine derivatives have been synthesized, starting from ring closure reactions of 3-hydrazino-4-(4'-fluoropheny1)-5-(prydin-4'-yl)-1,2,4-trizole (4) with 1,2-bioxygen compounds followed by the treatment with functional phosphorus compounds. The new systems obtained were evaluated as molluscicidal targets against some snails. Structures of these targets were elucidated upon their elemental and spectral data.
