3-Methyl-2-butenal → HCID 54518346, compound

Participants

Reaction Steps

120 Parts of 2-methyl-1-hepten-6-one, 40 parts of 3,3-dimethyl-acrolein and 10 parts of zinc oxide are heated for 5 hours at 180° C and a pressure of 60 atmospheres. 63.5 Parts of 2,10-dimethyl-2,4,10-undecatrien-6-one having a boiling point of 120° to 123° C at 0.1 mm is obtained analogously to Example 9. The yield is 91% of theory (based on 3,3-dimethyl-acrolein) at a conversion of 78% of theory.
