Telomerization of isoprene with diethylamine in the presence of catalytic amounts of palladium chloride and triphenylphosphine under carbon dioxide and/or using methanol as solvent gave three kinds of 2:1 adducts in good yields, one of which was found to be an adduct of new type.

High yields of tetrahydroanthraquinones are obtained by oxidizing a compound of the formula ##STR1## wherein R.sub.3 and R.sub.4 are the same or different and can be an alkyl group having one to eight carbon atoms or hydrogen. The reaction product thus produced is useful in the anthraquinone process for producing hydrogen peroxide.
