Architecture and synthesis of P,N-heterocyclic phosphine ligands

open access: yesBeilstein Journal of Organic Chemistry, 2020
Diverse P,N-phosphine ligands reported to date have performed exceptionally well as auxiliary ligands in organometallic catalysis. Phosphines bearing 2-pyridyl moieties prominently feature in literature as compared to phosphines with five-membered N ...

Homo- and heterodehydrocoupling of phosphines mediated by alkali metal catalysts

open access: yesNature Communications, 2019
Catalytic chemistry that involves the activation and transformation of main group substrates is relatively undeveloped and current examples are generally mediated by expensive transition metal species.

Phosphonate–Phosphinate Rearrangement

open access: yesThe Journal of Organic Chemistry, 2015
LiTMP metalated dimethyl N-Boc-phosphoramidates derived from 1-phenylethylamine and 1,2,3,4-tetrahydronaphthalen-1-ylamine highly selectively at the CH3O group to generate short-lived oxymethyllithiums. These isomerized to diastereomeric hydroxymethylphosphonamidates (phosphate–phosphonate rearrangement).

Mononuclear Copper(I) 3-(2-pyridyl)pyrazole Complexes: The Crucial Role of Phosphine on Photoluminescence

open access: yesMolecules, 2021
A series of emissive Cu(I) cationic complexes with 3-(2-pyridyl)-5-phenyl-pyrazole and various phosphines: dppbz (1), Xantphos (2), DPEPhos (3), PPh3 (4), and BINAP (5) were designed and characterized.

Carvone-Derived P-Stereogenic Phosphines: Design, Synthesis, and Use in Allene-Imine [3 + 2] Annulation.

open access: yesACS Catalysis, 2018
We have prepared a previously unreported family of P-stereogenic [2.2.1] bicyclic chiral phosphines through straightforward syntheses starting from the natural product carvone.

Photoswitchable phosphines in catalysis [PDF]

open access: yesChemCatChem, 2020
AbstractPhotoswitchable catalysts based on phosphorus ligands have been overlooked so far, despite the growing current interest for catalysts control through external stimuli. This review surveys the current knowledge in the field, including synthetic approaches to photoswitchable phosphines and their transition metal complexes, and applications in ...

Synthesis, Structure and Nickel Carbonyl Complexes of Dialkylterphenyl Phosphines.

open access: yesChemistry, 2018
The experimental and computational characterization of a series of dialkylterphenyl phosphines, PR2 Ar' is described. The new P-donors comprise five compounds of general formula PR2 Ar Dtbp 2 (R=Me, Et, iPr, c-C5 H9 and c-C6 H11 ); Ar Dtbp 2 = 2,6-C6 H3 -

Machine learning for identifying liver and pancreas cancers through comprehensive serum glycopeptide spectra analysis: a case‐control study

open access: yesMolecular Oncology, EarlyView.
This study presents a novel AI‐based diagnostic approach—comprehensive serum glycopeptide spectra analysis (CSGSA)—that integrates tumor markers and enriched glycopeptides from serum. Using a neural network model, this method accurately distinguishes liver and pancreatic cancers from healthy individuals.

The E3 ubiquitin ligase, RNF219, suppresses CNOT6L expression to exhibit antiproliferative activity

open access: yesFEBS Open Bio, EarlyView.
We identified RNF219 as a CCR4‐NOT complex‐interacting E3 ubiquitin ligase that targets the CCR4‐NOT subunit CNOT6L for ubiquitination. RNF219 directly binds to the DUF3819 domain of CNOT1 through its putative α‐helix spanning amino acids 521–542. Our findings also suggest that antiproliferative activity of RNF219 is at least partially mediated by ...
