摘要: Abstract Novel complexes of the type Pd(π-all)(Ar)(L) (all = CH 2 CMeCH , MeCHCHCH EtO CCHCHCH ; Ar C 6 Cl 5 2,3,5,6-C HCl 4 L PPh 3 SbPh ) were prepared and characterized by 1 H NMR spectroscopy. These shown to be particularly good model compounds for mechanistic studies allylic alkylation via π-allylpalladium complexes. Reductive elimination these proceeds a unimolecular, concerted pathway give, in regio- stereo-selective fashion, quantitative yields allylpolychlorobenzenes.
