摘要：

Chiral dithioether ligands have been tested in the model Pd-catalysed allylic alkylation reaction of (+/-)-3-acetoxy-1,3-diphenyl-1-propene with dimethyl malonate. giving high enantioselectivity (up to 81% e.e.) for the first time in this type of system. Pd(Il)-allylic intermediates, [Pd(eta (3)-1,3-Ph-2-C3H3)(dithioether)]PF6 were prepared and characterised both in solution by NMR spectroscopy and solid state. The X-ray structure for [Pd(eta (3)-1,3-Ph-2-C3H3)(L)]PF6 (L=(R,R)-7,8-O-isopropylidene-1,5-dithiacyclononane) was determined. (C) 2001 Elsevier Science Ltd. All rights reserved.
