syntheses et etudes de certains esters cycliques et polyesters phosphores
l'auteur explique le comportement des esters cycliques neutres vis -a- vis de l'eau ,de l'acide chlorhydrique , ainsi que la polymerisation des ethylphosphates cycliques d'ethylene et de propylene par des traces d'eau. les produits resultant de la plymerisation de ce dernicr phosphate cyclique sont plus complexes que ceux obtenus dans les memes conditions avec 1'et...
متن کاملDirect aerobic photo-oxidative syntheses of aromatic methyl esters from methyl aromatics using anthraquinone-2,3-dicarboxylic acid as organophotocatalyst.
This paper reports a useful method for facile direct syntheses of aromatic methyl esters from methyl aromatics by aerobic photo-oxidation using anthraquinone-2,3-dicarboxylic acid as an organophotocatalyst.
متن کاملAromatic Esters from the Liverwort, Isotachis japonica1
Bereits der Zusatz des durch bloßes Abspülen der Tiere mit Methanol gewonnenen Schleimextraktes an den isolierten Rattenuterus und das Meerschweinchenileum löste an diesen Organen Kontraktionen aus. Dieser stimulierende Effekt blieb auch nach Zugabe der Antagonisten gegenüber den üblichen in Organextrakten gelegentlich vorkommenden biologisch aktiven Begleitsubstanzen voll erhalten. Da die Wirk...
متن کاملMicellar effects on aromatic esters hydrolysis
The alkaline hydrolysis of two aromatic esters, 2-naphthyl acetate (2NA) and phenyl acetate (PhA) has been tackled in this work. The reaction has been followed in water and in the presence of cationic surfactants with different chain lengths: dodecyltrimethylammonium bromide (DTABr), tetradecyltrimethylammonium bromide (TTABr), and hexadecyltrimethylammonium bromide (CTABr) and the correspondin...
متن کاملNew asymmetric syntheses with boronic esters and fluoroboranes*
Efficient cleavage of sterically hindered boronic esters of asymmetric diols to recover both the diol and a more reactive borane derivative has been a challenging problem. A remarkable borosilicate glass-catalyzed cleavage with thionyl chloride and imidazole proved less useful than hoped for. Potassium bifluoride converts boronic esters to diols and alkyltrifluoroborates. These with chlorosilan...
