2-Methyl-4, 6-cyclohexadienaldehyde and n-butyraldehyde were treated with sodium in p-xylene to yield the aromatized “leaf alcohol reaction” product, 2-methyl-benzylalcohol, in a better yield than that with the cyclohexadienaldehyde alone. n-Butyric acid isolated from the reaction mixture unequivocally showed the operation of the “crossed Cannizzaro disproportionation” in this reaction, aliphatic aldehyde serving as the hydride donor. 2-Propyl-5-ethyl-4, 6-cyclohexadienaldehyde was obtained by the NaOH/H₂O-EtOH Michael-Aldol condensation of leaf aldehyde, gave 2-propyl-5-ethyl-benzylalcohol along with caproic acid.

On the basis of “leaf alcohol-reaction” mechanism, it was obtained following benzyl-alkohols; 2-methyl-, 2-propyl-, 2-methyl-5-ethyl-, 2-propyl-5-ethyl-benzylalcohol, from leaf alcohol and crotylalcohol.
