Development of Mononuclear (Arene) Ruthenium Complexes as Anticancer Agents: A Review [PDF]
(Arene)ruthenium complexes have displayed promising activity against cancer and showed fewer side effects compared to platinum-based drugs. Activity tuning of arene complexes have been explored by varying, amines, phosphines and other N^N, N^O, N^S ...

Room Temperature Ni(II) Catalyzed Hydrophosphination and Cyclotrimerization of Alkynes
The catalytic activity of nickel complexes in hydrophosphination involving secondary phosphines is not a commonly studied transformation. Beyond a small number of stand-out examples, many reports in the literature focus on the use of simple nickel salts.

Predicting the Air Stability of Phosphines
DFT calculations form the basis of a model capable of predicting the air stability of phosphines. The sensitivity of 18 primary phosphines is accounted for; the model also predicts the trend of increasing stability from phenylphosphine to ...

Phosphonate–Phosphinate Rearrangement
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).

Copper(I)-catalyzed asymmetric hydrophosphination of alkenyl azaarenes
Hydrophosphination of α,β-unsaturated carbonyl compounds is one of the most common methods to prepare chiral phosphines. Herein, a copper(I)-catalyzed asymmetric hydrophosphination of alkenyl azaarenes is developed by virtue of the electron-withdrawing ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Stoichiometric and Catalytic Synthesis of Alkynylphosphines
Alkynylphosphines or their borane complexes are available either through C–P bond forming reactions or through modification of the phosphorus or the alkynyl function of various alkynyl phosphorus derivatives.

Architecture and synthesis of P,N-heterocyclic phosphine ligands
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 ...
