“…Palladium complexes are of great interest due to their active role as catalysts in challenging organic syntheses [1][2][3][4][5][6] as well as due to their biological activity, especially as anticancer, antibacterial or antifungal agents. [7] These remarkable properties are mainly due to the transitional metal.…”

Palladium (II) complexes of three polydentate non‐planar bicyclo[4.4.0]decane ligands with at least one double bond and bridgehead cis‐substituents CH2OH or CH2OCH2 were prepared in order to investigate the role of stereochemistry and donor nucleophilicity in the Pd coordination. All ligands and their corresponding complexes were characterized using NMR, solid‐state NMR (ssNMR), HR‐MS, ATR‐IR, DSC‐TGA. For ligand cis‐1,4,5,8‐tetrahydro‐naphthalene‐4a,8a‐diyl‐dimethanol (L2) the X‐ray structure corresponded to the DFT optimised structure. The HR‐MS and thermal analysis data confirmed a complexation ratio: ligand/PdCl2 of 1/1. The experimental data as well as the computations are consistent with the structures proposed based on 13C‐ssNMR, namely palladium coordinates with one double bond and an oxygen atom for ligands with CH2OH groups and with both double bonds for the ligand with an etheric bridge, showing the prevalence of stereochemistry over donor nucleophilicity for such non‐planar ligands.

Palladacycles have been synthesized from Pd(OAc)2 and Schiff base ligands via C-H activation, to render dinuclear acetate-bridged compounds. The latter are starting materials for the sequence of reactions leading to the ensuing complexes. Treatment of the µ-acetate dinuclear complexes with aqueous sodium chloride in a typical metathesis reaction, gave the corresponding µ-chloride dinuclear complexes. Reaction of the latter with triphenylphosphine or with bis(diphenylphosphino)methane (dppm) in a 1:2 ratio, and ammonium hexafluorophosphate, gave the single nuclear complexes in a bridge-splitting reaction. The compounds were characterized by microanalysis (CHN), IR and 1 H and 31 P{ 1 H} NMR spectroscopy. The crystal structures of two of them were determined by single-crystal X-ray diffraction. Additionally, the performance of the synthetized palladacycles as catalysts has been evaluated in the Suzuki-Miyaura cross-coupling reaction: they are suitable for the cross coupling of a rather large number of substrates in high yields under mild conditions.
