Other names: Diallylmalonic acid diethyl ester; Propanedioic acid, di-2 … WebCationic nickel catalysts with monodentate phosphoramidites and Wilke's azaphospholene as ligands are highly regio- and enantioselective catalysts for the cycloisomerisation of diethyl diallylmalonate. WebDiethyl diallylmalonate (100 mg, 0.416 mmol) was added and the reaction mixture was stirred under nitrogen for 1 h at room temperature. After addition of diethyl ether (30 mL), the mixture was filtered through a plug of silica gel. The solvent was removed on the rotovap, and a crude GC-MS spectrum of a diluted (diethyl ether) aliquot was acquired. ellen kennedy berkshire community college
