Three palladium(II) complexes Pd(L)X (X = CH3CO2, Cl, I) of the conjugate base of 2-(diphenylphosphino)benzaldehyde benzoylhydrazone (HL) have been synthesized and characterized.Pd(L)(CH3CO2) is active in the catalytic hydrogenation of styrene, phenylacetylene and 1-octyne.While styrene is hydrogenated to ethylbenzene, alkynes are mainly hydrogenated to the corresponding olefins.Stable alkynylpalladium(II) complexes which are responsible for the loss of catalytic activity have been isolated and characterized.The X-ray structure of one of them, Pd(L)(CC-C6H5), has been determined together with that of the Pd(L)Cl complex.

Cross-coupling reactions, namely, the Suzuki?Miyaura, Heck, Sonogashira, Hiyama, Negishi, Kumada, and Hartwig?Buchwald, are the most powerful approaches in the formation of C?C, C?N, C?O, and C?S bonds for the complex organic scaffolds in drugs, natural products, organic materials, and fine chemicals. The nitrogen-based ligands have upper hands in these reactions because they are air stable, inexpensive, and easier to handle than the phosphorous counterparts. In this perspective, Schiff bases and N-heterocyclic carbenes have been explored extensively in terms of novel design and preparation as ligands in the coupling reactions. Facile recovery and reusability of these ligands make them eco-friendly and economical. A comprehensive outline on the progress in Schiff bases?metal complexes and NHC?metal complexes that mediated cross-coupling reactions with recent examples highlighted is reported (160 references).

A new, highly efficient in situ protocol (Cp2ZrCl2/LiAlH(OBu-t)3) is described for the generation of the Schwartz reagent which provides a convenient method for the amide to aldehyde reduction and the regioselective hydrozirconation-iodination of alkynes and alkenes. Highlighted are chemoselective reductions of benzamides derived by directed ortho metalation (DoM) chemistry, allowing the synthesis of valuable 1,2,3-substituted benzaldehydes. The single-step, three-component process proceeds in a very short reaction time, shows excellent functional group compatibility, and uses inexpensive and long-storage stable reducing reagents.

Preparation of the o-diphenylphosphinobenzaldehyde complexes of Pd(II) and Pt(II), with general formulae [MX2L2], [Pd 2Me2(mu-Cl)2L2] and [PdMeClL 2] where [M = Pd or Pt; X = Cl, Br, I and L = o- diphenylphosphinobenzaldehyde, {PPh2(o-C6H 4CHO)}], is reported here. All complexes have been characterized by elemental analysis, IR, NMR (1H, 13C, 31P and 195Pt) and UV-visible spectroscopy, that allowed the deduction of the stereochemistry for the complexes. The mononuclear complexes have been found to adopt the trans configuration in square-planar geometries. The molecular structure of trans-[PdCl2{PPh2(C6H 4CHO)}2] has been established by a single crystal X-ray diffraction study and confirms the spectroscopic conclusions.

Chiral dihydrobenzofuran units are frequently present in molecules with significant biological and pharmaceutical activities. Herein, we present the first enantioselective formal [4+1] annulation of Morita-Baylis-Hillman carbonates with o-quinone methides (o-QMs) catalyzed by a newly designed chiral phosphine catalyst. Under the mild and eco-friendly conditions, a wide range of polysubstituted dihydrobenzofurans were obtained in good yields with excellent enantioselectivities. (Figure presented.).

A sequential one-pot process for chemoselectively reducing sterically demanding N,N-diisopropylamides to aldehydes has been developed. In this reaction, amides are activated with EtOTf to form imidates, which are reduced with LiAlH(OR)3 [R = t-Bu, Et] to give aldehydes by hydrolysis of the resulting hemiaminals. The non-nucleophilic base 2,6-DTBMP remarkably improves reaction efficiency. The combination of EtOTf/2,6-DTBMP and LiAlH(O-t-Bu)3 was found to be optimal for reducing alkyl, alkenyl, alkynyl, and 2-monosubstituted aryl N,N-diisopropylamides. In contrast, EtOTf and LiAlH(OEt)3 in the absence of base were found to be optimal for reducing extremely sterically demanding 2,6-disubstituted N,N-diisopropylbenzamides. The reaction tolerates various reducible functional groups, including aldehyde and ketone. 1H NMR studies confirmed the formation of imidates stable in water. The synthetic usefulness of this methodology was demonstrated with N,N-diisopropylamide-directed ortho-metalation and C-H bond activation.

Herein, we report the use of phosphinoazomethinylate salts as chiral efficient ligands for the copper-catalyzed asymmetric conjugate addition (ACA) of dialkylzinc to various enones. These tridentate P,N,O ligands are straightforwardly obtained in a one-step procedure from commercially available enantiopure alpha-aminoacids. Performing the conjugate addition in the greener AcOEt solvent, high enantioselectivities were reached for both cyclic and acyclic enones ranging between 72% to 98% ee and 96% to >99%, respectively. The 2/1 Cu/ligand ratio required to obtain high enantioselectivities, led us to envisage a copper-copper bi-metallic catalytic system for this transformation.
