Dimerization of propylene was studied with several bis(salicylaldehyde)nickel(II) complexes in combination with aluminum co-catalysts, eventually in the presence of ancillary phosphine ligands. The effects of the type and relative amount of aluminum co-catalyst as well as the nature of nickel precursors were examined. The results clearly indicated that the nickel precursors characterized by the presence of either bulky substituents or electron-withdrawing groups on the salicylaldehyde ligands displayed high activity. The catalytic performance was also remarkably modified in the presence of phosphine ligand, and the regioselectivity in the dimers was directed to 2,3DMB with incorporation of basic and bulky PCy3 into the nickel catalysts, especially at the temperature below 0 C. A preliminary UV-Vis study was performed in order to detect the variation of nickel species involved in the dimerization process. The bis(2-hydroxy-1-naphthaldehyde)nickel (1d) system exhibited an extremely high productivity (TOF up to 262,000 h-1) as well as a moderate regioselectivity to 2,3DMB (65.6%) in the dimerization of propylene under appropriate reaction parameters.

A convenient synthetic strategy toward N-acylguanidines via a sequential one-pot multicomponent carbonylation/amination reaction has been developed. The compounds were readily obtained via an N-cyanobenzamide intermediate formed from the Pd(0)-catalyzed carbonylative coupling of cyanamide and aryl iodides or bromides. Subsequent amination with a large variety of amines provided the final N-acylguanidines, with the overall formation of one C-C and two C-N bonds, in moderate to excellent yields. The substrate scope was found to be wide and the methodology was used to produce over 50 compounds, including 29 novel molecules. Furthermore, three separate nitrogen-containing heterocycles were prepared from the N-acylguanidines synthesized using the developed multicomponent, carbonylative method.

Post-Ugi transformation reactions are well known to form molecular complexity, fused heterocyclic backbones. Existence of alkyne moiety in the structure of Ugi-4CR products allows post condensation cyclizations establishing carbon-carbon bonds by means of metal-catalyzed reactions or metal-free reactions. Synthesis of different heterocyclic backbones such as 2-oxindoles and spiroindolines can be constructed based on alkyne cyclization of post-Ugi reaction.

The recently introduced pump-probe fragmentation action spectroscopy reveals a unique observation of excited state vibrational coherence (430-460 fs) in the isolated metal complex [Ag2(Cl)(dcpm)2)]+ (dcpm = bis(dicyclohexylphosphino)methane) containing the [Ag2Cl]+ scaffold. After photoexcitation by an 1XMCT transition (260 nm) in an ion trap, an unexpected correlation between specific fragment ions (loss of HCl/Cl- vs loss of dcpm) and the phase of the wave packet is probed (1150 nm). Based on ab initio calculations, we assign the primary electronically excited state and ascribe the observed coherences (72-78 cm-1) to contain predominantly Ag-Ag stretch character. We propose specific probe absorption and vibronic coupling at the classical turning points to switch remarkably early on between the different fragmentation pathways. The overall excited state dynamics are fitted to a multiexponential decay with time constants: 0.2-0.4/3-4/19-26/104-161 ps. These findings open new perspectives for further dynamics investigations and possible applications in photocatalysis.

Pregnane X receptor (PXR) is a ligand-dependent transcription factor that is considered to be a potential therapeutic target for multiple diseases. Herein, we report the development and structure-activity relationship studies of a new series of hPXR agonists. Focusing on our recently developed silanol-sulfonamide scaffold, we developed the potent hPXR agonist 28, which shows good selectivity over hLXRalpha and beta, hFXR, and hRORalpha and gamma. Examination of the structure-activity relationship suggested a possible strategy to manipulate the selectivity. Docking simulation indicated the presence of an additional binding cavity and polar contacts in the ligand-binding pocket of hPXR. This information should be helpful for the future development of more potent and selective hPXR ligands.

Nowadays, computational studies are very important for the elucidation of reaction mechanisms and selectivity of complex reactions. However, traditional computational methods usually require an estimated reaction path, mainly driven by limited experimental implications, intuition, and assumptions of stationary points. However, the artificial force induced reaction (AFIR) method in the global reaction route mapping (GRRM) strategy can be used for unbiased and automatic reaction path searches for complex reactions. In this account, we highlight applications of the AFIR method to a variety of reactions (organic, organometallic, enzymatic, and photochemical) of complex molecular systems. In addition, the AFIR method has been successfully used to rationalise the origin of stereo- and regioselectivity. The AFIR method can be applied from small to large molecular systems, and will be a very useful tool for the study of complex molecular problems in many areas of chemistry, biology, and material sciences. (Figure presented.).

With their mechanistic novelty and various modalities of reactivity, transition metal unsaturated carbene (alkenylidene) complexes have emerged as versatile intermediates for new reaction discovery. In particular, the past decade has witnessed remarkable advances in the chemistry of metal vinylidenes and allenylidenes, leading to the evolution of a diverse array of new catalytic transformations that are mechanistically distinct from those developed in the previous two decades. This review aims to provide a survey of the recent achievements in the development of organic reactions that make use of transition metal alkenylidenes as catalytic intermediates and their applications to organic synthesis.
