Synthesis of a series of new platinum organometallic complexes derived from bidentate Schiff-base ligands and their catalytic activity in the hydrosilylation and dehydrosilylation of styrene

The synthesis and properties of a novel class of platinum complexes containing Schiff bases as O,N-bidentate ligands is described as are the solution and solid state properties of the uncomplexed ligands. The platinum complexes were prepared from [PtBr2(COD)] (COD = 1,5-cyclooctadiene) and N-(2-hydroxy-1-naphthalidene)aniline derivatives in the presence of base (NaOBut). Instead of a substitution reaction to afford cationic species, the addition of the Schiff base ligands results in both the formal loss of two equivalents of bromide and addition of hydroxide to the COD ligand of the complexes. It is proposed that this reaction proceeds through a cationic platinum complex [Pt(N-O)(COD)]Br which then undergoes addition of water and loss of HBr. An example of a dinuclear platinum complex in which two cyclo-octene ligands are bridged by an ether linkage is also reported. The platinum complexes were evaluated as catalysts for the hydrogenative and dehydrogenative silylation of styrene, the resulting behaviour is substituent, time and temperature dependent.

Preparation and properties of inclusion compounds of transition-metal complexes of cycloocta-1,5-diene and norbornadiene with cyclodextrins

Inclusion compounds of rhodium and platinum complexes of cycloocta-1,5-diene (COD) and norbornadiene (NBD) with cyclodextrins were prepared. Two-to-one (cyclodextrin to guest) inclusion compounds were obtained in high yields in a crystalline state by the treatment of β-cyclodextrin (β-CD) with bis(μ-halo)bis(η4-cycloocta-1,5-diene)dirhodium, [Rh(μ-X)(COD)]2 (X = Cl, Br, I), and bis(μ-chloro)bis(η4-norbornadiene)dirhodium, [Rh(μ-Cl)(NBD)]2. The formation of inclusion compounds is selective. One-to-one inclusion compounds were obtained by the reaction of β-CD with (cycloocta-1,5-diene)platinum dihalides, Pt(COD)X2 (X = Cl, Br, I), in high yields, while γ-CD formed 1:1 inclusion compounds with Pt(COD)I2 but not with Pt(COD)Cl2. α-Cyclodextrin did not form inclusion compounds with any transition-metal complexes of cyclooctadiene and norbornadiene. The inclusion compounds are thermally stable and do not liberate the guest when heated to 200°C in vacuo at which temperature the nonincluded guest [Rh(μ-Cl)(COD)]2 already decomposed. The inclusion compounds were characterized by 1H NMR, IR, UV, and circular dichroism spectra. A large induced Cotton effect was observed with β-CD-[Rh(μ-Cl)(COD)]2. The 1H NMR spectrum of [Rh(μ-Cl)(COD)]2 in the presence of β-CD shows two sets of resonances for two different CD species that are assigned to free β-CD and the complexed β-CD, respectively. The binding mode will be discussed.
