Ion-Mobility Mass Spectrometry for the Rapid Determination of the Topology of Interlocked and Knotted Molecules

A rapid screening method based on traveling-wave ion-mobility spectrometry (TWIMS) combined with tandem mass spectrometry provides insight into the topology of interlocked and knotted molecules, even when they exist in complex mixtures, such as interconverting dynamic combinatorial libraries. A TWIMS characterization of structure-indicative fragments generated by collision-induced dissociation (CID) together with a floppiness parameter defined based on parent- and fragment-ion arrival times provide a straightforward topology identification. To demonstrate its broad applicability, this approach is applied here to six Hopf and two Solomon links, a trefoil knot, and a [3]catenate.

A versatile and efficient palladium-meta-terarylphosphine catalyst for the copper-free sonogashira coupling of (hetero-)aryl chlorides and alkynes

A novel meta-terarylphosphine ligand, CyPhine, was developed and found to be a highly active promoter of copper-free Sonogashira cross-coupling reactions when combined in situ with a palladium source. The evolutionary m-terarylphosphine ligand architecture was able to impose significant performance advantages over its biarylphosphine congeners. An expedient and versatile protocol was also devised with an emphasis on substrates applicable to the fine-chemicals industry by featuring a diverse range of challenging, electronrich aryl chlorides and terminal alkynes. The Pd-CyPhine catalyst was able to deliver products in excellent yields with efficient substrate utilization, which minimizes the generation of commonly formed byproducts, and the reaction is tolerant of a variety of substrates with unprotected functional groups.

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 52409-22-0 is helpful to your research. Electric Literature of 52409-22-0

Chemo-, regio-, and stereoselective Heck-Matsuda arylation of allylic alcohols under mild conditions

Heck arylation with allylic alcohol is extremely challenging due to chemo-, regio-, and stereoselective scrambling. Here we report a mild protocol for the alcohol selective beta- and alpha-arylation of allylic and cinnamyl alcohols respectively with aryldiazonium salts. The steric and electronic parameters of the alkene play a prominent role in the regioselectivity.

Synthesis of fluoroalkyl palladium and nickel complexes via decarbonylation of acylmetal species

The synthesis and characterization of a series of fluoroalkyl palladium(II) and nickel(II) complexes via decarbonylation of the corresponding acylmetal species is reported. At palladium(II), labile supporting ligands such as tri-o-tolylphosphine are required to achieve decarbonylation within 30 min at 85 C. In contrast, decarbonylation at (PPh3)2Ni(C(O) RF)(OCORF) (RF = fluoroalkyl) complexes proceeds rapidly at or below room temperature.

Metal- and additive-free oxygen-atom transfer reaction: an efficient and chemoselective oxidation of sulfides to sulfoxides with cyclic diacyl peroxides

Metal- and additive-free oxidation of a series of sulfides/thioketones has been achieved using cyclic diacyl peroxides as mild oxygen sources. This protocol features simple manipulation, high chemo- and diastereoselectivity, and a broad substrate scope (up to 42 examples), tolerates many common functional groups, and is scalable and applicable to the late-stage sulfoxidation strategy. A preliminary mechanistic study by quantum mechanical calculations suggests that a single two-electron transfer process is energetically more favorable, and indicates the reactivity of cyclic diacyl peroxides distinct from conventional acyclic acyl peroxides.

Enantioselective synthesis of tetrahydroquinolines, tetrahydroquinoxalines, and tetrahydroisoquinolines via Pd-Catalyzed alkene carboamination reactions

A catalyst composed of Pd2(dba)3 and (S)-Siphos-PE provides excellent results in Pd-catalyzed alkene carboamination reactions between aniline derivatives bearing pendant alkenes and aryl or alkenyl halides. These transformations generate tetrahydroquinolines and tetrahydroquinoxalines that contain quaternary carbon stereocenters with high levels of asymmetric induction. In addition this catalyst also effects the asymmetric synthesis of tetrahydroisoquinolines via related transformations of 2-allylbenzylamines. In contrast to most other approaches to the asymmetric synthesis of these compounds, which frequently involve functional group interconversion or a single C-C or C-N bond-forming event, the carboamination reactions generate both a C-N bond, a C-C bond, and a stereocenter.
