Kinetics and mechanism of cyclopalladation for [Pd(S)(Bn₂Medptn)](BF₄)₂ (S = solvent, Bn₂Medptn = N,N″-dibenzyl-N′-methyl-3,3′-diaminodipropylamine) and its derivatives

The kinetics of the cyclopalladation for [Pd(CH₃CN)-(Bn₂Medptn)](BF₄)₂ (Bn₂Medpln = N,N″-dibenzyl-N′-methyl-3,3′-diaminodipropylamine) and ils derivatives confirmed the concerted mechanism where both the electrophilic attack of the palladium(II) center toward the ortho benzyl carbon and the nucleophilic interaction of the basic solvent with the ortho proton are operative in the activation process for the cyclopalladation.
