Transition metal-catalyzed cross-coupling reaction is an efficient method of carbon-carbon bond formation.e.g.palladium-catalyzed reaction for vinyl triflates with orga-notin reagents provides a good example of this kind.The authors and othershave shown that palladium could insert into the carbon-oxygen bond of phenyl fluoroal-kanesulfonate(ArOSO_2R_f1)via oxidative addition.Very recently,the transmetallationof this arylpalladium(Ⅱ)species with organozinc reagents giving the correspondingalkylbenzenes has also been reported.Herein we wish to present another novel cross--coupling reaction of phenyl fluoroalkanesulfonates(1)with an organometallic reagent,allyltributyltin(2)in the presence of catalytic amounts of tetrakis(triphenylphos-phine)-palladium to give the corresponding allyl benzenes(3)in good yields.
