The organotitanium compounds RTi (OPr-i)/sub 3/ (R = Ar, Me) and RTi(NEt/sub 2/)/sub 3/ (R=CH/sub 2/=CH, PhCH=CH, CH/sub 2/=CHCH/sub 2/) react with allyl halides in the presence of palladium complexes under mild conditions to give the allyldemetallation products. In the case of RTi(OPr-i)/sub 3/ compounds, an efficient cross-coupling catalyst is bis (..pi..-allylpalladium chloride), whereas reactions involving RTi(NEt/sub 2/)/sub 3/ are catalyzed by tetrakis(triphenylphosphine)palladium.
