Enolic monoether and diether of adipic dialdehyde such as 6-methoxy-5-hexene-1-al, 1,6-dimethoxy-1,5-hexadiene, 1,6-bis-(2 hydroxy propoxy)-1,5-hexadiene are prepared by heating to a sufficiently high temperature for a Cope rearrangement, e.g., 150° to 450° C. of the corresponding monoether or diether of 1,5-hexadiene-3,4-diol. |
