摘要: Abstract Reactions of KPPh2 with the dimeric cyclopalladated complex {Pd(N∩C)(μ-Cl)}2 1 derived from N,N-dimethylbenzylamine were studied using different reagent ratios, temperature, reaction time, concentrations and solvents. Complex 3, μ-Cl-μ-PPh2 analog 1, was obtained in 76% yield one-hour 1:1 ratio dimer THF at rt. ortho-(Diphenylphosphino)benzylamine 4 synthesized 58% by reacting 4.5 equiv. A possible mechanism aminophosphine formation is proposed on basis experimental data including 31P{1H} NMR spectra mixtures.
