Zinc-acetic acid promoted reductive carbon-nitrogen bond cleavage reaction of alpha-aminoketones

Scope and limitation of the reductive cleavage reaction of alpha-aminoketone systems with zinc-acetic acid are described. The carbon-nitrogen bond cleavage reaction was applicable to a wide range of alpha-aminoalkyl aryl ketones possessing various substituents on the aromatic ring. In contrast, alpha-aminoalkyl alkyl ketones with protons at the alpha’-position or alpha-aminoesters were sluggish to the carbon-nitrogen cleavage reaction.

5-Norbornene-2-carboxylic acid: Another catalytic mediator for Catellani-type reactions

Mediators play a central role in Catellani-type reactions. Herein we reported the discovery of inexpensive 5-norbornene-2-carboxylic acid (N4) as a general catalytic mediator (20 mol%) to facilitate ortho C?H activation and the following C?C bond formation of aryl iodides. Firstly, a cooperative catalytic system comprising N4 and a palladium/XPhos complex was developed for the novel Catellani/redox-relay Heck cascade to construct tetrahydronaphthalenes and indanes that contain a quaternary carbon stereogenic center. The striking feature of this work was the avoidance of stoichiometric NBE mediator that are usually required for Catellani-type reactions. Then, preliminary results demonstrated that N4 could act as a general catalytic mediator to replace NBE for other Catellani-type reactions, which will undoubtedly inspire future developments in the field of cooperative catalysis. Finally, control experiments indicated that the carboxylic acid moiety of N4 plays an essential role in its ability to serve as a superior mediator.

Efficient homo-coupling reactions of heterocyclic aromatic bromides catalyzed by Pd(OAc)2 using indium

Homo-coupling reactions of heterocyclic aromatic bromides smoothly proceeded with cat-Pd(OAc)2, indium, and LiCl in DMF to afford exclusively symmetric biaryls possessing heterocyclic aromatic ring in good to excellent yields.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 1532-97-4, you can also check out more blogs about1532-97-4

Selective synthesis of (E)-triethyl(2-arylethenyl)silane derivatives by reaction of aryl bromides with triethyl vinylsilane catalysed by a palladium-tetraphosphine complex

Cis, cis, cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane / 0.5 [PdCl(C3H5)]2 system catalyses the Heck reaction of vinylsilane derivatives with a range of aryl bromides with high ratio substrate/catalyst in good yields. The formation of mixtures of styrene, (E)-triethyl(2-arylethenyl)silane and triethyl(1-arylethenyl)silane derivatives was observed in some cases. Very high selectivities (up to 100%) in favour of the formation of (E)-triethyl(2-arylethenyl)silane derivatives were obtained in the presence of sodium acetate as base. With other bases such as potassium carbonate, the formation of large amounts of styrene derivatives was observed. The reaction tolerates several functions such as fluoro, trifluoromethyl, methoxy, dimethylamino, acetyl, formyl, benzoyl, carboxylate, nitro or nitrile. Moreover, turnover numbers up to 10,000 can be obtained for this reaction.

Enantioselective template-directed [2+2] photocycloadditions of isoquinolones: Scope, mechanism and synthetic applications

A strategy for the enantioselective [2+2] photocycloaddition of isoquinolones with alkenes is presented, in which the formation of a supramolecular complex between a chiral template and the substrate ensures high enantioface differentiation by shielding one face of the substrate. Fifteen different electron-deficient alkenes and ten different substituted isoquinolones undergo efficient photocycloaddition, yielding the cyclobutane products in excellent yields and with outstanding regio-, diastereo- and enantioselectivities (up to 990 ee). The mechanism of the reaction is investigated by means of triplet sensitization/quenching and radical clock experiments, the results of which are consistent with the involvement of a triplet excited state and a 1,4-biradical intermediate. The variety of functionalized cyclobutanes obtained using this approach can be further increased by straightforward synthetic transformations of the photoadducts, allowing rapid access to libraries of compounds for various applications.

Luminescent Pt(ii) complexes bearing dual isoquinolinyl pyrazolates: Fundamentals and applications

A series of four Pt(ii) metal complexes with trans-arranged isoquinolinyl azolates have been prepared, [Pt(Lx)2], x = 1-4, (1-4). The associated chelates possess various substituents; namely: one t-butyl (But) at the 6-position (L1), two But groups at the 5,7-positions (L2), one dip (2,6-di-isopropylphenyl) group at the 6-position (L3), and a single dip group at the 4-position of the 1-isoquinolinyl fragment (L4), respectively. Crystal structures of 1 and 4 were determined to shed light on the relationship of photophysics and packing arrangements. Their photophysical properties were measured and compared, for which the solid-state emission spectra of 2 and 4 are nearly identical to the solution spectra of all the Pt(ii) complexes, showing the formation of isolated molecular entities. In contrast, the Pt(ii) complexes 1 and 3 are found to be sensitive to their morphological states and external stimulus. This is confirmed by the gradual red-shifting of the emission with increasing concentration in the PMMA matrix, and the eventual formation of the broadened, metal-metal-to-ligand charge transfer (MMLCT) emission, by (i) wetting with acetone and drying in air, or (ii) grinding with a mortar and pestle, respectively. Organic light-emitting diodes (OLEDs) were also fabricated using multiple layered architecture and lowered doping concentration (e.g. 8 wt%), the latter is for avoiding dopant aggregation in the emitting layer. The associated OLED performances (i.e. etamax = 11.5%, 8.5%, and 11.2% for 1, 2 and 3) confirmed their suitability and potential as dopants for phosphorescent OLEDs.
