Relevant academic research and scientific papers

Synthesis of 0,0-dialkyl phthalimidophosphonothioates and dialkyl phthalimidophosphonates

Dialkyl phthalimidophosphonites were reacted with sulfur to synthesize 0,0-dialkyl phthalimidophosphonothioates. Reaction of phthalimide with trialkyl phosphites in carbon tetrachloride gives dialkyl phthalimidophosphonates.

Fungicidal composition for seed dressing

The present invention relates to a fungicidal composition intended for the protection of the multiplication products of cultivated plants, containing: (a) 2-(4-chlorobenzylidene)-5,5-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol; (b) one or more fungicides suitable for the protection of the said multiplication products, optionally one or more insecticides, (c), an agriculturally acceptable inert vehicle and an agriculturally acceptable surfactant. The invention also relates to a method for protecting the multiplication products of plants against fungal diseases using these compositions.

Preparation of O,O-dialkyl phthalimido-phosphonothioate

The present invention is directed to an improved method for preparing O,O-dialkyl phthalimidophosphonothioate (hereinafter alternatively referred to as "phosphonothioate"), corresponding to the formula STR1 wherein each R is independently an alkyl group having from 1 to 4 carbon atoms, comprising reacting O,O-dialkyl phosphoramidothioate with phthalic anhydride in the presence of a tertiary amine catalyst.

Process for preparing cyclicdicarboximido-substituted phosphonothioates

Cyclicdicarboximido-substituted phosphonothioates corresponding to the formula EQU1 WHEREIN R represents phthalimido, monomethyl substituted phthalimido, 4-cyclohexene-1,2-dicarboximido or monomethyl substituted 4-cyclohexene-1,2,-dicarboximido are prepared by a method which comprises reacting an appropriate O,O-diloweralkyl phosphorochloridothioate with an appropriate N-alkali metal cyclicdicarboximide reactant in the presence of a catalytic amount of a 1-(loweralkyl)imidazole and an inert tertiary alcohol as a reaction medium.
