Abstract

The reactions of PdCl2(L-L) [L-L = Ph2PCH2PPh2(dppm), Ph2PCH2CH2PPh2(dppe) and Ph2PCH2CH2CH2PPh2(dppp)] with equivalent amount of (Ph2P(S)NHP(S)Ph-2)(dppaS(2)) gave the complexes [Pd(L-L)(dppaS(2)-H)]ClO4 [L-L = dppm (1), dppe (2), dppp (3)]. The different synthetic route was used for complex 2 by using of Pd(dppe)Cl-2 and K[N(PSPh2)(2)] as starting materials (2a). All of these complexes have been characterized P-31{H-1} NMR, IR and elemental analyses. The complexes 2, 2a and 3 were crystallographically characterized. The coordination geometry around the Pd atoms in these complexes distorted square planar. Six membered dppaS2-H rings are twist boat conformations in three complexes. (C) 2007 Elsevier Ltd.
