Conclusions

  1. 1.

    The organotitanium compounds RTi(OPr-i)3 (R=Ar, Me) and RTi(NEt2)3 (R=CH2=CH, PhCH=CH, CH2=CHCH2) react with allyl halides in the presence of palladium complexes under mild conditions to give the allyldemetallation products.

  2. 2.

    In the case of RTi(OPr-i)3 compounds, an efficient cross-coupling catalystis bis (ir-allylpalladium chloride), whereas reactions involving RTi(NEt2)3 are catalyzed by tetrakis(triphenylphosphine)palladium.
