Compound: 1-(Furan-2-yl)propan-1-one, is researched, Molecular C7H8O2, CAS is 3194-15-8, about 1,4-Addition in the furan series. I. Condensation of benzylmagnesium bromide with α-furyl ketones. Author is Berreby, Edgar; Morizur, Jean P.; Wiemann, Joseph.
A mixture of 27.5 g. 2-acetylfuran in 50 cc. ether was refluxed 1 hr. with PhCH2MgBr prepared from 42.75 g. PhCH2Br and hydrolyzed with HCl to give 10 g. of the starting material and 34 g. of a mixture, b0.01 82-92°. This mixture was redistilled to give 18% dibenzyl, b5 115-17°, 20% 1-phenyl-2-furyl-2-propanol, b5 123°, and 30% 2-acetyl-3-benzyl-2,3-dihydrofuran, b7 131°. Similar treatment of ethyl 2-furyl ketone gave 31.5 g. of a mixture containing 11% dibenzyl, 24% 1-phenyl-2-furyl-2-butanol, b6 136°, and 24% 2-propionyl-3-benzyl-2,3-dihydrofuran, b6 131°. N.M.R. and ir data are given.
