Water-tolerant enantioselective carbonyl-ene reactions with palladium(II) and platinum(II) Lewis acid catalysts bearing BINAP

Palladium(II) and platinum(II) Lewis acid catalysts bearing BINAP have been proved to be water-tolerant in enantioselective carbonyl-ene reactions, thus arylglyoxal monohydrate could be used directly as substrate achieving good to excellent enantioselectivities as high as 95.4% e.e.. The enantioselective carbonyl-ene reactions using phenylglyoxal monohydrate as substrate with four alkenes including methylenecyclohexane, 2,3-dimethyl-1-butene, 2,4,4-trimethyl-1-pentene and alpha-methylstyrene, were investigated demonstrating comparable or even higher yields and enantioselectivities in comparison with the corresponding carbonyl-ene reactions using dry phenylglyoxal as substrate for both palladium(II)-BINAP catalyst and platinum(II)-BINAP catalyst. The palladium(II) and platinum(II)-BINAP catalyzed enantioselective carbonyl-ene reactions between 4-methylphenylglyoxal monohydrate and the four alkenes were also investigated affording enantioselectivities between 76.2% and 91.8% e.e.. A mechanism involving the coordination of arylglyoxal and 2,2-dihydroxy-1-phenylethanone with chiral catalyst was proposed to interpret the enantioselective carbonyl-ene reactions using arylglyoxal monohydrate as substrate.

Chiral separation of substituted phenylalanine analogues using chiral palladium phosphine complexes with enantioselective liquid-liquid extraction

Chiral palladium phosphine complexes have been employed in the chiral separation of amino acids and phenylalanine analogues in particular. The use of (S)-xylyl-BINAP as a ligand for the palladium complex in enantioselective liquid-liquid extraction allowed the separation of the phenylalanine analogues with the highest operational selectivity reported to date. 31P NMR, FTIR, FIR, UV-Vis, CD and Raman spectroscopy methods have been applied to gain insight into the binding mechanism of the amino acid substrates with the chiral palladium phosphine complexes. A complexation in a bidentate fashion is proposed.

Conformational flexibility of palladium BINAP complexes explored by X-ray analyses and DFT studies

Several crystal structures and a theoretical DFT structure of the important catalyst (BINAP)PdCl2 (BINAP: 2,2′-bis(diphenylphosphino)-1, 1′-binaphthyl) have been determined. The conformational flexibilities of the BINAP backbone and of the phenyl rings do not seem to be coupled. Two novel parameter have been introduced that define the Π-Π stacking between the phenyl and biaryl rings in systems similar to the BINAP ligand, as well as the delta angle that is sensitive to the important interaction of the exchangeable ligands of the palladium with the equatorial phenyl rings of the BINAP. Furthermore, the calculated bite angle is 3° larger than the experimentally determined bite angles.

Visible-Light-Induced Palladium-Catalyzed Dehydrogenative Carbonylation of Amines to Oxalamides

The palladium-catalyzed oxidative carbonylation of amines toward the synthesis of oxalamides has been established around 30 years ago and it usually needs the presence of (over)stoichiometric amounts of oxidant. In this work, the first transformation of this type in which the oxidant was replaced by visible light is described. The new approach uses a simple robust Pd complex, which can even be partially recycled. A mechanistic reason is provided and supported by control experiments and EPR studies, showing that PdI was formed and Pd0 was the active species. Both nitrogen- and the intermediate acyl radical can be detected. Moreover, the formation of hydrogen was confirmed by gas GC.

Hydroxy complexes of palladium(II) and platinum(II) as catalysts for the acetalization of aldehydes and ketones

The acetalization of aldehydes or ketones is a reaction of synthetic interest in organic chemistry that is commonly catalyzed by Bronsted or Lewis acids. We have found that a class of Pd(II) and Pt(II) complexes of the type [(P-P)M(μ-OH)]2+2 (P-P = a series of diphosphines; M = Pd, Pt) are effective catalysts for the acetalization of a variety of aldehydes and ketones in the presence of alcohols or glycols. The use of epoxides instead of alcohols resulted in lower rates and yields. The rate and yield of the reaction is not affected by the size of the diphosphine in the series dppe, dppp, dppb. Attempts to perform the reaction in a stereoselective fashion showed no difference depending on whether regular achiral catalysts or catalysts modified with chiral diphosphines were used.
