THE ALPHA'-OXIDATION OF ALPHA-ALKOXY ENONES USING MANGANESE(III) ACETATE IN COMBINATION WITH CARBOXYLIC-ACIDS Demir, Ayhan Sıtkı; SAATCIOGLU, A (Informa UK Limited, 1993-01-01) The alpha'-oxidation of cyclic derivatives of alpha-alkoxy-alpha,beta-unsaturated ketones using manganese(III)acetate in the presence of various carboxylic acids provided a convenient synthesis of 5-acyloxy-2-alkoxy-2-cyclopentenones and 6-acyloxy-2-alkoxy-2-cyclohexenones.
A facile synthesis of various butenolides Tanyeli, Cihangir (Informa UK Limited, 2000-01-01) The synthesis of alpha'-acyloxy-alpha,beta-unsaturated cyclic ketones from the corresponding alpha,beta-unsaturated cyclic ketones by using manganese (III) acetate in combination with 2-chloropropionic acid followed by subsequent Arbuzov and intramolecular Horner-Emmons cyclization reactions provided a convenient synthetic pathway to various butenolides 4a-d.
AN EFFICIENT BUTENOLIDE ANNULATION VIA ALPHA'-CHLOROACETOXYLATION OF ENONES USING MANGANESE(III) ACETATE AND CHLOROACETIC ACID DEMIR, AS; AKGUN, H; Tanyeli, Cihangir; SAYRAC, T; WATT, DS (1991-09-01) The alpha'-chloroacetoxylation of alpha,-beta-unsaturated ketones using manganese(III) acetate and chloroacetic acid followed by Arbuzov reaction and intramolecular Horner-Emmons olefination provided a convenient synthesis of annulated 2-buten-4-olides.
Synthesis of a novel poly(arylene ether ketone) and its conducting composites with polypyrrole Selampinar, F; Akbulut, Ural; Yildiz, E; Gungor, A; Toppare, Levent Kamil (1997-08-01) The synthesis of a 1,3-bis(4-fluorobenzoyl)-5-tert-butyl benzene and hexafluoro bisphenol A based poly(arylene ether ketone) (PEK) was described. The electrically conductive composites of polypyrrole (PPy) and PEK were formed by electropolymerization of pyrrole on a PEK coated platinum electrode in a medium containing water and p-toluenesulfonic acid as the solvent and the electrolyte, respectively. The electrical conductivity of the composites was found to be between 1 and 4 S/cm. The polypyrrole/poly( eth...
