Transition metal and main group compounds bearing eta1-indenyl ligands have figured importantly since the beginnings of organometallic chemistry, and continue to attract considerable attention. The novel reactivity of the transition metal derivatives and the utility of the main group species as ligands in the development of chiral metallocene pre-catalysts have led to a renaissance in this field of study. The dynamic behavior of these eta1-indenyl complexes has also been examined: the preponderance of evidence points to a circumambulatory process involving sequential [1,5]-elementotropic shifts that proceed via short-lived isoindene intermediates.

The [2 + 2 + 2] cyclotrimerization of diynes and nitrile provides an efficient method for the synthesis of pyridine and its derivatives which can be extended in the total synthesis of natural products. Use of Grubbs type ruthenium catalysts in the cyclotrimerization reaction expands the applicability of Ru(II) catalysts. Two plausible pathways, viz. metathesis and non-metathesis for the cyclotrimerization reaction between a diyne and a nitrile are elucidated with Grubbs second generation and Hoveyda-Grubbs catalysts using DFT techniques. A ruthenacyclobutene like complex is obtained as a stable intermediate in the metathesis pathway while the formation of a five membered metallacycle is invoked to explain the non-metathesis pathway using a decomposed catalyst. The study reveals the influence of N-substituents on N-heterocyclic ligands (NHC) as well as substituent on carbene ligand in controlling the energetic of both metathesis and non-metathesis pathways. Incorporating NHC ligand with reduced steric influence in catalyst design is desirable for improving the efficiency of cyclotrimerization reaction of alkynes with nitriles. If the catalyst is not decomposed, metathesis is the reaction route and the preferred product will be a benzene derivative. The heterocycle formation observed by Perez-Castells et al. (Org. Lett.,14, 2012, 4982?4985) in presence of excess activated nitriles can only be described using the decomposed catalyst through a non-metathesis pathway.

Rhodium-Catalyzed ortho-Selective C-F Activation and Hydrodefluorination of Heterocycle-Substituted Polyfluoroarenes: Dominated by Phosphine Ligands

In this paper, the ortho-selective mono-hydrodefluorination and/or di-hydrodefluorination of heterocycle substituted polyfluoroarenes were catalyzed by rhodium complexes along with phosphine ligands and ethanol as hydride source. Diverse partially fluorinated aromatics had been synthesized by this method. The study of the mechanism demonstrated that ethanol was the sole hydride source in the cycle of hydrodefluorination. Furthermore, the phosphine ligand controlled chemoselectivity had been discussed by monitoring experiment.

Selective Synthesis of (Benzyl)biphenyls by Successive Suzuki-Miyaura Coupling of Phenylboronic Acids with 4-Bromobenzyl Acetate under Air Atmosphere

An efficient Pd-catalyzed cross-coupling reaction of phenylboronic acids and benzyl carbonates was developed, producing diarylmethanes. Benzyl acetates could also be used as coupling partners instead of benzyl carbonates, affording diarylmethanes in comparable yields. This reaction can be conducted under air atmosphere without any care for moisture and oxygen. The ester function showed an intermediate reactivity between chloro and bromo groups. This property facilitated the selective synthesis of diverse (benzyl)biphenyls by successive Suzuki-Miyaura coupling reactions using bromo- and chloro-substituted benzyl esters with two types of boronic acids.

Palladium acetate assisted synthesis of five-membered N-polyheterocycles

The metal-assisted synthesis of heterocyclic compounds is known to be one of the extremely developing as well as significant concepts of organic chemistry. Because of their expensive, complex working of the instrument and difficult procedures, the methodologies used earlier for the heterocycle synthesis were less amicable to the researchers. The Pd(OAc)2-mediated cyclic reactions have been recognized to be very effective for both the stereoselective as well as regioselective formation of the 5-membered N-bearing heterocyclic compounds. The different uses of palladium acetate, as a catalyst in the formation of 5-membered N-containing polyheterocycles, are covered in this review article.

Copper salts as additives in gold(I)-Catalyzed reactions

The right combination: CuI and CuII salts can advantageously replace silver additives in AuI-catalyzed reactions. On the basis of reactivity studies and NMR experiments, it is believed that anion metathesis between CuYn (Y=OTf, BF4, PF6, SbF6) and [R3PAuCl] takes place to give [R 3PAu]Y. As this process is slow, there is no fast decay of the active species, thus allowing large-scale reactions, even at high temperatures, with low loadings of the gold complex. Copyright

Formic acid as a hydrogen storage material-development of homogeneous catalysts for selective hydrogen release

Formic acid (FA, HCO2H) receives considerable attention as a hydrogen storage material. In this respect, hydrogenation of CO2 to FA and dehydrogenation of FA are crucial reaction steps. In the past decade, for both reactions, several molecularly defined and nanostructured catalysts have been developed and intensively studied. From 2010 onwards, this review covers recent advancements in this area using homogeneous catalysts. In addition to the development of catalysts for H2 generation, reversible H2 storage including continuous H2 production from formic acid is highlighted. Special focus is put on recent progress in non-noble metal catalysts.
