Reaction of aminoalcohols with butadiene catalyzed by palladium complexes. Preliminary communication

The aminoalcohols 1 , react with 2 equivalents of butadiene in the presence of catalytic quantities of bis (acetylacetonato)palladium/triphenylphosphine to give exclusively the corresponding N-octadienyl amninoalcohols. In the presence of excess butadiene, subsequent O-octadienylation occurs only for N-octadienylimino-diethanol 2g , affording the monoether 4g . O-octadienylation of 2a-f and 4g can be effected by the addition of molar quantities of triethylamine to the reaction mixture.
