There is currently a growing interest in imino derivatives of compounds such as thiadiazoles and other groups whose extended π-electron systems enhance their photophysical properties. These also show low toxicity strong antifungal activity, making them effective against fungal pathogens crops. For the above reasons, first part paper, structure selected analogs was considered, detailed spectroscopic analyses were conducted focusing on excited state intramolecular proton transfer (ESIPT)...
Abstract Several classes of arylphosphorus acid amides have been tested in reactions with alkali metal solutions liquid ammonia. The outcomes such depend on the structures starting materials. Generally, two processes – Birch reduction or cleavage P–aryl bond can be operative. Diarylphosphinic tend to undergo double afford bis(cyclohexadienyl)phosphinic amides.
Diastereomerically pure phenylphosphonous acid‐borane l ‐menthyl ester N , ‐diethylamide was obtained through the fractional crystallization of a diastereomeric mixture compounds synthesized from PhPCl 2 ‐menthol, diethylamine, and BH 3 · THF. Treatment racemic or diastereomerically derivatives with sodium in liquid ammonia followed by addition an electrophile led to formation phosphinous acid‐amides. Surprisingly, these undergo preferential P–N bond cleavage under Birch reduction conditions.
Abstract Several strategies for the development of synthesis P‐chiral organophosphorus compounds with (L)‐prolinol as a source chirality have been examined. A reaction L ‐prolinol set different alkyl/arylphosphonous acid diamides led in most cases to quantitative formation appropriate bicyclic oxazaphospholidines complete diastereo and enantioselectivity. The latter were reacted BH 3 complex formed borane analogues submitted structural modifications leading tertiary phosphine‐boranes....
W polskim rolnictwie użytkowanych jest 3,8 mln budynków inwentarskich o wartości 70 mld zł. Stopień zużycia wynosi 75%. Roczny poziom nakładów inwestycyjnych wzrósł w latach 2000–2006 z ok. 700 do 1300 Przewidywany dalszy wzrost nakładów, jednak jego tempo najbliższych 2–3 będzie niższe niż dotychczas.
Abstract Synthesis and modifications of new chiral phospholene-based scaffolds are described. The construction base molecules was accomplished via McCormack synthesis. Separation single P-epimers with column chromatography on silica gel.
The resolution of racemic 1-phenylphosphin-2-en-4-one 1-oxide (2), was achieved through the fractional crystallization its diastereomeric complexes with (4R,5R)-(-)-2,2-dimethyl -α,α,α',α'-tetraphenyl-dioxolan-4,5-dimethanol (R,R-TADDOL) followed by liberation individual enantiomers 2 flash chromatography on silica gel columns. process furnished two 99.1 and 99.9% e.e. at isolated yields 62 59% (counted for single enantiomer), respectively. absolute configurations were established means...
Abstract Arylphosphorus acid amides undergo generally two processes under Birch reduction conditions ‐ or cleavage of the P‐aryl bond.
Abstract The reaction of tertiary arylphosphine oxides with sodium in liquid ammonia is strongly influenced by the substrate structure.
Abstract We present the development of method for refitting ReaxFF parameters a system consisting mixed transition metal oxides. have tested several methods allowing to calculate differences between vectors forces acting on atoms obtained from reference DFT simulation and parameters-dependent ReaxFF. conclude that footrule yields best among investigated options. then validate using hematite supported (TiO 2 ) n clusters. The results indicate refitted allow obtain much better geometries...
