Participants

Reaction Steps

100 Parts of methyl norbornyl ketone, 50 parts of 3,3-dimethyl-acrolein and 15 parts of zinc oxide are heated for 5 hours at 180° C and a pressure of 55 atmospheres. 85.7 Parts of (4-methyl-1,3-pentadienyl)-norbornyl ketone is obtained having a boiling point of 110° C at 0.01 mm analogously to Example 9. The yield is 88% of theory at a conversion of 80% of theory based on 3,3-dimethylacrolein.
