Synthesis, Characterization and Fungicidal Activity of Some Dialkyl Alkylphosphonates and Dialkyl Phenylphosphonates
Some dialkyl alkylphosphonates and dialkyl phenylphosphonates were synthesized by the reactions between trialkyl phosphite and alkyl/aryl halide in the presence of benzene. The synthesized compounds were characterized by elemental analysis, thin layer chromatography (TLC), fourier –transform infrared, ( 1 H, 13 C) nuclear magnetic resonance (NMR) spectroscopic techniques. In vitro fungicidal ac...

15 صفحه اولA New synthesis of functionalized imidazo[2,1-b][1,3]thiazines with thiohydantoins, isocyanides and dialkyl acetylenedicarboxylates
The reaction of stoichiometric amounts of dialkyl acetylenedicarboxylates with alkyl isocyanides and 5,5-diaryl thiohydantoins in toluene and catalytic amount of p-TSA afforded imidazo[2,1-b][1,3]thiazines in good overall yields
متن کاملNITROIMIDAZOLES XI [I]. SYNTHESES OF DISUBSTITUTED NITROIMIDAZOLYLQUINOLINES
Reaction of substituted-aniline (8) with ethyl (l-methyl-5-nitroimidazole-2- carbonyl) acetate (9) gave 4-hydroxy-2-(l-methyl-5-nitro-2-imidazolyl)- substituted-quinolines (lo), which were converted to compound 11 with phosphorus oxychloride. Substituted-2-(l-methyl-5-nitro-2-imidazo1yl)-4.- methyl-(or phenyl-) quinolines (14) were prepared through the reaction of 2- acetyl-5-nitro-1-methy...
متن کاملDesulfuration of dialkyl thiophosphoric acids by a pseudomonad.
A strain of Pseudomonas acidovorans used the organophosphorus pesticide breakdown products, ionic O,O-diethyl phosphorothioate and ionic O,O-diethyl phosphorodithioate, as sulfur sources. The growth yields from the thiophosphates and sulfate were 3.6 to 4.1 kg of protein per mol of sulfur. Elemental sulfur and sulfide also served as sulfur sources but gave lower growth yields.
