Reactions of Cp*Ir(CO)2 with pentafluorobenzonitrile : half-sandwich iridium complexes Cp*Ir(CO)(p-C6F4CN)(X)
The reaction of Cp*Ir(CO)2 (1) with pentafluorobenzontrile in the presence of a base afforded the diaryl complex Cp*Ir(CO)(p-C6F4CN)2 (4). The reaction proceeds via the metallacarboxylic acid Cp*Ir(CO)(p-C6F4CN)(COOH) (2). ...
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 ...
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.
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 ...
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 ...
Zwitterionic base-stabilized digermadistannacyclobutadiene and tetragermacyclobutadiene
The syntheses of a zwitterionic base-stabilized digermadistannacyclobutadiene and tetragermacyclobutadiene supported by amidinates and low-valent germanium amidinate substituents are described. The reaction of the amidinate ...
Stability and Reactivity of Cyclometallated Naphthylamine Complexes in Pd–C Bond Insertion Reactions with Coordinated Alkynylphosphanes
Phenylbis(phenylethynyl)phosphane PhP(C≡CPh)2 coordinates regiospecifically to the α-methyl-chiral ortho-platinated and -palladated naphthylamine units at the positions trans to the nitrogen donors. The P→Pt coordination ...
Selective Arylation and Vinylation at the α Position of Vinylarenes
In intermolecular Heck reactions of styrene and vinylarenes, the aryl and vinyl groups routinely insert at the β position. However, selective insertion at the α position has been very rare. Herein, we provide a missing ...
