Radical addition of 3-oxopropanenitriles to 1,3-butadiene derivatives promoted by (NH4)(2)Ce(NO2)(6) and Mn(OAc)(3) afforded 5-ethenyl-4,5-dihydrofuran-3-carbonitriles in low to good yields. These dihydrofurans were characterised by IR, H-1-NMR, C-13-NMR and HRMS spectra. All radical additions performed via CAN and Mn(OAc)(3) were occurred on the terminal double bond on dienes. A mechanism for the formation of the dihydrofurans was proposed.
