SYNTHÈSE DE NOUVEAUX INITIATEURS. GÉNÉRATION IN SITU DE COMPOSÉS PEROXYGÈNES PAR ACTION DU PERCARBONATE DE SODIUM. APPLICATION [Agrave] LA DESTRUCTION DE TOXIQUES ORGANOPHOSPHORES ET/OU SOUFRES
摘要:
New initiators 1-7, analogues of tetra-acetylethylenediamine, have been prepared and their use in the in situ generation of peroxyacids by reaction with sodium peroxycarbonate described. The kinetics of perhydrolysis of these initiators in aqueous solution under different conditions of temperature and pH, as well as the use of these new "complex peroxygenated systems" in the destruction of organophosphorus and sulfur toxins and pollutants, have been studied.
低价钌诱导硝基烯烃 1-Phenyl-2-Nitropropene-1 中硝基和 CC 双键同时还原
摘要:
AbstractThe reduction of 1‐phenyl‐2‐nitropropene‐1 (1) on using ruthenium complexes was studied in detail in order to correlate this method with those previously recorded in the literature for the hydrogenation of nitroolefins. A variety of products was isolated by varying the reaction temperature and solvent. Among them was 1‐phenyl‐2‐propylamine (4), completely reduced from the selective both double bond and nitro group. 1‐Phenyl‐2‐propanol (5) was observed due to reduction of phenylacetone at 125 °C in the presence of ruthenium catalyst. When reaction temperature was lower than 125 °C, by employing RuCl2(PPh3)3 complex, 1‐phenyl‐2‐nitropropane (2) and phenylacetone (3) were obtained, respectively. Ru‐BINAP complexes were attempted to produce chiral amine from starting material 1‐phenyl‐2‐nitropropene‐1 (1).
