Isolation of a bis(oxazol-2-ylidene)-phenylborylene adduct and its reactivity as a boron-centered nucleophile
An isolable phenylborylene species supported by two oxazol-2-ylidene ligands was synthesized and structurally characterized. Computational studies revealed the presence of lone-pair electrons on the boron atom in this ...
A rationally designed nitrogen-rich metal-organic framework and its exceptionally high CO2 and H2 uptake capability
On the way towards a sustainable low-carbon future, the design and construction of chemical or physical adsorbents for CO2 capture and clean energy storage are vital technology. The incorporation of accessible nitrogen-donor ...
Asymmetric hydroarsination reactions toward synthesis of alcohol functionalised C-chiral As–P ligands promoted by chiral cyclometallated complexes
The asymmetric hydroarsination reactions between diphenylarsine and 3-diphenylphosphanyl-but-3-en-1-ol and 2-diphenylphosphanyl-prop-2-en-1-ol have been achieved using the organopalladium complex containing ortho-metallated ...
Molecule-based water-oxidation catalysts (WOCs) : cluster-size-dependent dye-sensitized polyoxometalates for visible-light-driven O2 evolution
From atomic level to understand the cluster-size-dependant behavior of dye-sensitized photocatalysts is very important and helpful to design new photocatalytic materials. Although the relationship between the photocatalytic ...
The original reactivity of a phosphole-substituted Fischer carbene complex
In an unprecedented transformation, a phosphole-substituted Fischer carbene complex reacts with styrene to give an annelated phosphole derivative.
New thioether–dithiolate complexes of Cp∗Ir and some reactivity features
The reaction of [Cp∗IrCl2]2 (Cp* = η5 − C5Me5) with the tridentate 3-thiapentane-1,5-dithiolate ligand, S(CH2CH2S−)2 (tpdt), led to the formation of [Cp∗Ir(η3 − tpdt)] (1) in 81% isolated yield. Subsequent reactions of 1 ...
Synthesis and reactivity of cationic iridium aminocarbenes derived from terminal alkynes and 2-aminopyridines
The reaction of a terminal alkyne (RCCH) and 2- aminopyridine (R′C5NH3NH2) with the dinuclear species [Cp*IrCl2]2 afforded the cationic aminocarbene derivatives Cp*Ir(Cl)[ C- (CH2R)NHC5NH3R′] via a hydroamination and ...
A base-stabilized lead(I) dimer and an aromatic plumbylidenide anion
The aromatic low-valent lead analogue of an indenyl anion (see scheme; 1) undergoes oxidation with SnCl2 to form the base-stabilized lead(I) dimer 2. Reduction of 2 with lithium regenerates 1. These compounds were characterized ...
Synthesis, optical resolution, and stereochemical properties of a rationally designed chiral C–N palladacycle
A novel racemic tertiary amine, 1-(2,5-diisopropylphenyl)-N,N-dimethylethanamine, was synthesized from 2,5-diisopropylbenzaldehyde via a multistep approach in high overall yield. The ortho palladation of this ligand was ...
Enantioselective addition of diphenylphosphine to 3-methyl-4-nitro-5-alkenylisoxazoles
An enantioselective Michael addition reaction of diphenylphosphine to substituted alkenylisoxazoles has been developed. The reaction proceeds efficiently under mild conditions with high yields (up to 99%) and moderate to ...
