Palladium-mediated 11C-carbonylations using aryl halides and cyanamide

A robust and high-yielding radiochemical synthesis of 11C-N-cyanobenzamides using a palladium-mediated aminocarbonylation with 11C-CO, aryl halides and cyanamide is described. The bidentate ligand 1,1?-bis(diphenylphosphino)ferrocene provided 11C-N-cyanobenzamides from aryl-iodides, bromides, triflates and even chlorides in 28-79% radiochemical yield after semi-preparative HPLC. To further highlight the utility of this method, novel 11C-N-cyanobenzamide analogs of flufenamic acid, meflanamic acid, dazoxiben and tamibarotene were synthesized in 34-71% radiochemical yields.

Palladium-Catalyzed Hydrohalogenation of 1,6-Enynes: Hydrogen Halide Salts and Alkyl Halides as Convenient HX Surrogates

Difficulties associated with handling H2 and CO in metal-catalyzed processes have led to the development of chemical surrogates to these species. Despite many successful examples using this strategy, the application of convenient hydrogen halide (HX) surrogates in catalysis has lagged behind considerably. We now report the use of ammonium halides as HX surrogates to accomplish a Pd-catalyzed hydrohalogenation of enynes. These safe and practical salts avoid many drawbacks associated with traditional HX sources including toxicity and corrosiveness. Experimental and computational studies support a reaction mechanism involving a crucial E-to-Z vinyl-Pd isomerization and a carbon-halogen bond-forming reductive elimination. Furthermore, rare examples of C(sp3)-Br and ?Cl reductive elimination from Pd(II) as well as transfer hydroiodination using 1-iodobutane as an alternate HI surrogate are also presented.

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 53199-31-8 is helpful to your research. Related Products of 53199-31-8

Pd-Catalyzed Stereoselective 1,2-Aryboration of Alkenylarenes

The palladium-catalyzed highly regio- and diastereoselective arylboration of alkenylarenes has been developed. This chemistry afforded the benzylic boronic esters with a broad substrate scope, which are valuable synthetic intermediates for organic synthesis. The chiral anion phase-transfer strategy was designed for this transformation to realize the regio-, diastereo-, and enantioselective control of this reaction simultaneously.

Palladium nanoparticles in glycerol: A versatile catalytic system for C-X bond formation and hydrogenation processes

Palladium nanoparticles stabilised by tris(3-sulfophenyl)phosphine trisodium salt in neat glycerol have been synthesised and fully characterised, starting from both Pd(II) and Pd(0) species. The versatility of this innovative catalytic colloidal solution has been proved by its efficient application in C-X bond formation processes (X=C, N, P, S) and C-C multiple bond hydrogenation reactions. The catalytic glycerol phase could be recycled more than ten times, preserving its activity and selectivity. The scope of each of these processes has demonstrated the power of the as-prepared catalyst, isolating the corresponding expected products in yields higher than 90%. The dual catalytic behaviour of this glycerol phase, associated to the metallic nanocatalysts used in wet medium (molecular- and surface-like behaviour), has allowed attractive applications in one-pot multi-step transformations catalysed by palladium, such as C-C coupling followed by hydrogenation, without isolation of intermediates using only one catalytic precursor.

Palladium-catalysed direct cross-coupling of secondary alkyllithium reagents

Palladium-catalysed cross-coupling of secondary C(sp3) organometallic reagents has been a long-standing challenge in organic synthesis, due to the problems associated with undesired isomerisation or the formation of reduction products. Based on our recently developed catalytic C-C bond formation with organolithium reagents, herein we present a Pd-catalysed cross-coupling of secondary alkyllithium reagents with aryl and alkenyl bromides. The reaction proceeds at room temperature and on short timescales with high selectivity and yields. This methodology is also applicable to hindered aryl bromides, which are a major challenge in the field of metal catalysed cross-coupling reactions.

Both complexes are more cytotoxic to a number of human cancer cell lines than cisplatin. Moreover, complex 1 is more active than auranofin as the reference gold compound against a panel of several human tumor cell lines. Chemosensitivity tests completed on cisplatin sensitive and resistant cell lines have confirmed that both complexes were able to overcome cisplatin resistance. The complexes successfully inhibited the enzymes thioredoxin reductase (TrxR) and glutathione reductase (GR). The cellular uptake of both gold and palladium of the complexes was studied, which indicated a high biological stability of the complexes. The complexes 1 and 2 increase the production of ROS in HCT-15 cells. In addition, these complexes induce major levels of cancer cell death by apoptosis.
