Abstract :
Reactions of KPPh2 with the dimeric cyclopalladated complex {Pd(N∩C)(μ-Cl)}21 derived from N,N-dimethylbenzylamine were studied using different reagent ratios, temperature, reaction time, concentrations and solvents. Complex 3, the μ-Cl-μ-PPh2 analog of 1, was obtained in 76% yield in the one-hour reaction using the 1:1 ratio of dimer 1 and KPPh2 in THF at rt. ortho-(Diphenylphosphino)benzylamine 4 was synthesized in 58% yield by reacting complex 1 with 4.5 equiv. of KPPh2 in THF at rt. A possible mechanism of the aminophosphine formation is proposed on the basis of the experimental data including 31P{1H} NMR spectra of reaction mixtures.
