Versuchsvorschrift

The ethynylation of 212 g of 6,10-dimethylundeca-3-en-2-on-10-ol obtained by aldol condensation of hydroxycitronellal and acetone with acetylene was worked out in the same manner as in example 9 except that hydroxycitronellal was used in place of pseudoionone and 269 g of a crude product was thus obtained.
