摘要：

In this paper we report the synthesis and structural characterisation (when L=PBz(3) and PPh2Np) of the compounds [Pd(dba)L-2] (where L, PPh2Np 1, PPh(2)An 2, PPhNp2 3 and PBz(3) 4; Np, 1-naphthyl; An, anthracenyl; Bz, benzyl; and dba, dibenzylideneacetone) from [Pd-2(dba)(3)] and the corresponding phosphine. All these complexes with the exception of 4 retain their structures in solution. The P-31-NMR spectrum of 4 is both solvent and temperature dependent. Under an SO, atmosphere the reaction between [Pd-2(dba)(3)] and PBz(3) gave the novel dimer [Pd-2(mu-dba)(mu-SO2)(PBz(3))(2)] 5, which has been structurally characterised. In this dimer both the dba and SO2 ligands bridge the two metal centres. (C) 1999 Elsevier Science S.A. All rights reserved.
