Cross‐Dehydrogenative Coupling Reactions With Redox‐Active Guanidine Reagents

Chemistry – A European Journal, EarlyView.
ABSTRACT Cross‐dehydrogenative coupling (CDC) reactions are attractive and environmentally friendly ways to form new C‐C and other element‐element bonds. Here, we report the first CDC reactions triggered by a redox‐active guanidine reagent. N‐phenyltetrahydroisoquinoline and derivatives with electron‐donating and withdrawing substituents at the N ...

Silica‐Supported Mononuclear Methyl‐Platinum Complexes Stabilized by Trimethylphosphine—Synthesis, Structure, and Reactions Under Reducing Conditions

Chemistry – A European Journal, EarlyView.
The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...

Coordination Chemistry of Boron Subphthalocyanine With BINOL Derivatives: Unexpected Oxidation to Oxa[4]Helicene and Properties of the Resulting Axially Coordinated Complexes Containing Oxa[4]Helicene and/or BINOL Derivatives

Chemistry – A European Journal, EarlyView.
Treatment of BINOL with a boron subphthalocyanine derivative resulted in the formation of a complex coordinated to an oxa[4]helicene derivative, which is generated via a ring‐closure reaction of BINOL. In contrast, treatment of the monomethyl ether of 1,1′‐bi‐2‐naphthol (BINOL) afforded the expected axially coordinated complex.

Tribochemical Surface Modification of Silicon

Chemistry – A European Journal, EarlyView.
Mechanical scribing activates silicon surfaces by generating reactive sites that spontaneously graft alcohol‐, thiol‐, and alkyne‐terminated molecules under ambient conditions. Within 10 s, high‐coverage, electroactive organic layers form without light, heat, or applied voltage, offering a rapid tribochemical route to functional silicon interfaces for ...

Electrochemiluminescence of Heteroleptic Iridium(III) Complexes Featuring Substituted 2,4‐diphenylpyridinato Ligands

Chemistry – A European Journal, EarlyView.
Five heteroleptic iridium(III) complexes bearing cyclometalated 2,4‐diphenylpyridinato ligands were synthesized and their electrochemiluminescence (ECL) investigated. Two different coreactants were evaluated: tri‐n‐propylamine and benzoyl peroxide under anodic and cathodic potentials, respectively.

The Radical Chemistry of 2,3‐Diguanidinopyridines: Coordination and Visible‐Light Photochemistry

Chemistry – A European Journal, EarlyView.
Substitution at the pyridine core of 2,3‐diguanidinopyridines was used to develop novel redox‐active molecules with three interconvertible redox states. They are applied as redox‐active ligands in coordination chemistry. Visible‐light irradiation of the pyridine N‐benzylated molecules leads to photoconversion to a higher‐energetic isomer.

Redox‐Switchable Optical and Magnetic Properties in a Self‐Assembled Hexanuclear Ni(II) Double‐Decker Complex

Chemistry – A European Journal, EarlyView.
A triangular double‐decker Ni6 complex self‐assembles from Ni(II), TMEDA, and a triphenylene tris dioxolene non‐innocent ligand, with two face‐to‐face tris‐semiquinone decks held by a strong covalent C─C interaction. This rigid scaffold delivers four reversible ligand‐centered redox events: oxidation switches on an intense near‐infrared band and ...

A Homoleptic Copper(I) Acetylene Complex

Chemistry – A European Journal, EarlyView.
Ligand substitution of weakly coordinated N2 in [(N2)Cu{Al(ORF)4}] (RF = C(CF3)3) leads to the homoleptic acetylene complex [Cu(C2H2)3]+[Al(ORF)4]−, which was characterized by single crystal x‐ray diffraction, NMR, and Raman spectroscopy, as well as by extensive quantum chemical calculations. ABSTRACT We report the synthesis and characterization of the
