Reaction Steps

10 parts of cyclobutylcarboxylic acid chloride in tetrahydrofuran is hydrogenated over 10% palladium on carbon catalyst, to provide cyclobutylcarboxaldehyde. 25 parts of triphenylphosphoranylidene-2-propanone and 6.3 parts of the cyclobutylcarboxaldehyde in 60 parts by volume of benzene under nitrogen are refluxed for 8 hours. The solvent is removed by evaporation under reduced pressure to provide 4-cyclobutyl-3-buten-2-one.
