CuI complexes containing a multidentate and conformationally flexible dibenzylidene acetone ligand (dbathiophos): Application in catalytic alkene cyclopropanation

The synthesis and characterisation of a multidentate conformationally flexible ligand based on the dibenzylidene acetone core structure, dbathiophos (1), is described. Ligand 1 has a high affinity for cationic and neutral Cu I species. Three unique CuI complexes (4-6) are reported showing that the ligand backbone of dbathiophos is hemilabile, and able to adopt different 1,4-dien-3-one conformational geometries around CuI. Complexes 4 and 6 both effectively catalyse the cyclopropanation of styrene with ethyl diazoacetate at low catalyst loadings (1 mol% Cu). The Royal Society of Chemistry 2011.

Transition metal-catalyzed reactions of 3-Aza-2-oxabicyclo[2.2.1]hept-5-enes

Background: Transition metal catalysts are becoming increasingly more important in organic synthesis and are being used to catalyze novel reactions that allow for more efficient synthesis of many pharmaceuticals. Transition metal-catalyzed reactions of 3-aza-2-oxabicyco[2.2.1]hept-5-enes provide efficient synthetic pathways to generate a diverse range of biologically and synthetically useful products. 3-Aza-2-oxabicyclic alkenes undergo three main types of reactions: reductive N-O bond cleavage, C-O bond cleavage, and modification of the alkene component. Objective: The purpose of this review is to summarize and discuss the transition metal-mediated reactions of 3-aza-2-oxabicyclo[2.2.1]hept-5-enes, including the mechanisms of reactions based on the transition metal used, the different stereo-and regiochemical outcomes of reactions with this asymmetrical substrate, and the biological importance of exploring these reactions. Conclusion: It is clear from the review of the topic that a vast amount of work has been done in this area, and transition metals have been used to control the regio-and stereoselective reactions of 3-aza-2-oxabicyclic alkenes to create biologically active and synthetically useful products. The transition metal-catalyzed reactions of 3-aza-2-oxabicyclic alkenes proceed through three general reactions: through cleavage of the N-O bond, cleavage of the C-O bond, and modification of the alkene component. Without the use of transition metals, the substrate would not be activated and these reactions would not be possible. The use of transition metals opens up an array of new reactions that have the ability to create different functional groups with different regio-and stereoselectivities based on the metal and conditions used. The products made through these transition metal-catalyzed reactions can be useful as antibiotics, siderophores, and carbocyclic nucleosides such as noraristeromycin and carbocyclic polyoxin C.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 224311-51-7 is helpful to your research., Reference of 224311-51-7

Heterometallic iodoplumbates modified by copper(I) or silver(I) with viologens

Cu/Ag(I) were introduced into iodoplumbate systems to produce two new heterometallic iodoplumbates with viologen as templates, i.e. (PV)2(Pb2Cu2I10) (1) and [(BV)(Pb2AgI7)]n (2) (PV2+?=?propyl viologen, BV2+?=?benzyl viologen), in which the common connection of PbI6 units have been remarkably altered. In (PV)2(Pb2Cu2I10) (1), two PbI6 octahedra are bridged by two CuI4 tetrahedra via face-sharing to give a (Pb2Cu2I10)4? cluster, but the ternary one-dimensional polymeric (Pb2AgI7)n 2n? of [(BV)(Pb2AgI7)]n (2) is assembled from edge-sharing AgI4 tetrahedra and PbI6 octahedra. Their optical band gaps and fluorescence were also discussed. The absorption edges of haloplumbates could be engineered by introduction of suitable conjugated molecules as templates.

Modular synthesis of triarylmethanes through palladium-catalyzed sequential arylation of methyl phenyl sulfone

Triarylmethanes, which are valuable structures in materials, sensing and pharmaceuticals, have been synthesized starting from methyl phenyl sulfone as an inexpensive and readily available template. The three aryl groups were installed through two sequential palladium-catalyzed C-H arylation reactions, followed by an arylative desulfonation. This method provides a new synthetic approach to multisubstituted triarylmethanes using readily available haloarenes and aryl boronic acids, and is also valuable for the preparation of unexplored triarylmethane-based materials and pharmaceuticals.

Synthesis and Application of Planar Chiral Cyclic (Amino)(ferrocenyl)carbene Ligands Bearing FeCp? Group

New cyclic (amino)(ferrocenyl)carbene (CAFeC) ligands containing the Cp? group have been developed as a modification of their prototype Cp version. The generation of the new carbenes was indirectly confirmed by trapping experiments in which a carbene precursor was reacted with sulfur or [IrCl(cod)]2 in the presence of a base. The electronic properties of the new CAFeCs were evaluated by determining the Tolman electronic parameter (TEP) of the Ir dicarbonyl complex [IrCl(CO)2(CAFeC)] that was synthesized via [IrCl(cod)(CAFeC)]. It was revealed that the donor strengths of the new CAFeCs were very high and comparable to those of cyclic (amino)(alkyl)carbenes (CAACs). The influence of the steric effect on the enantioselectivity by changing Cp to the Cp? group of CAFeCs was confirmed to be significant in an Ir-catalyzed asymmetric transfer hydrogenation of cyclic N-sulfonylimine where CAFeCs were used as chiral ligands.
