On January 31, 2019, Bityukov, Oleg V.; Vil’, Vera A.; Lukashin, Nikita V.; Cherednichenko, Aleksandr G.; Nikishin, Gennady I.; Terent’ev, Alexander O. published an article.Product Details of 517-23-7 The title of the article was Solvent-free silica gel mediated decarboxylation of C-O coupling products of β-diketones and β-oxo esters with malonyl peroxides. And the article contained the following:
Silica gel was found to mediate decarboxylation of tetracarbonyl compounds with a free carboxylic group prepared from β-dicarbonyl compounds and malonyl peroxides to give I [R1 = Me; R2 = Me, CH2Ph, (CH2)2C(O)CH3, etc.; R1R2 = (CH2)3, (CH2)4, O(CH2)2; R3 = Me, OEt; R4 = CHEt2, CH(n-Bu)2, c-C4H7, c-C5H9]. Under solvent-free heterogeneous conditions silica gel effectively acts as a mediator of C-O coupling with further decarboxylation at 120 °C. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Product Details of 517-23-7
