Reaction Steps

The above prepared mixture (18 parts) was admixed with p-toluenesulfonic acid (0.9 part) and xylene (54 parts) and refluxed for 2 hours, during which by-produced water was eliminated by azeotropic distillation. The reaction mixture was treated as in Example 1 to give 2-n-pentyl-2-cyclopentenone in a yield of 96 %.
