Synthesis of Mixed Phosphine–Phosphine Oxide Ligands by Rh(I)‐Catalyzed C─H Bond Alkylation

open access: yesChemCatChem, EarlyView.
An efficient method for the synthesis of mixed phosphine–phosphine oxide ligands via Rh(I)‐catalyzed C─H bond alkylation of biarylphosphines was developed. The resulting hemilabile ligands demonstrate high reactivity in Pd‐catalyzed Buchwald–Hartwig coupling with ammonia, achieving excellent yields. This work highlights the potential of mixed phosphine–

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates

open access: yesChemCatChem, EarlyView.
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Schottky Diodes and Thin Films Based on Copolymer: Poly(aniline-co-toluidine)

open access: yesActive and Passive Electronic Components, 2009
Poly(aniline-co-o-toluidine) (PANI-co-POT) thin films were deposited on indium tin oxide- (ITO-) coated glass substrates by electrochemical polymerization under cyclic voltammetric conditions from aniline-co-o-toluidine monomer in an aqueous solution of ...

Copper Photoredox‐Catalyzed Allylation of Imines with Allylic Bromides

open access: yesChemCatChem, EarlyView.
[Cu(neocuproine)(DPEphos)]PF6 ([Cu(NN)(PP)]+) has been developed as a copper photocatalyst for the allylation of imines with allylic bromides. The transformation can be applied to a variety of imines, and the mechanism is believed to involve the direct addition of an allylic radical to the C═N bond.

Mg Plating in Nonethereal Electrolyte Solutions: Fact or Misconception?

open access: yesChemSusChem, EarlyView.
An overview of Mg electrochemistry in both ethereal and nonethereal electrolyte systems was provided. Comprehensive reviewing on the electrochemical Mg plating/stripping activity reaffirms that only a limited range of solvents support reversible Mg plating/stripping.

Critical Pitfalls in the Flow Cytometric Analysis of Mast Cells in Patients With Systemic Mastocytosis

open access: yesCytometry Part A, EarlyView.
ABSTRACT Systemic mastocytosis (SM) is a neoplastic disease characterized by abnormal mast cell (MC) activation and proliferation. Accurate diagnosis often relies on flow cytometry to detect aberrant CD25, CD2, and CD30 expression on MCs in bone marrow (BM).
