NHC-catalyzed ester activation : access to sterically congested spirocyclic oxindoles via reaction of α-aryl esters and unsaturated imines
Carboxylic esters can be readily obtained at low cost. Therefore, asymmetric catalytic activation of esters should provide useful strategies for organic synthesis. Here we report a N-heterocyclic carbene (NHC)-mediated ...
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 ...
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.
Counterion dependence on the synthetic viability of NHC-stabilized dichloroborenium cations
The synthetic viability of several N-heterocyclic carbene stabilized dichloroborenium cations [NHC·BCl2]+ (NHC = (RC)2(NR′)2C; 1, R = R′ = Me; 2, R = H, R′ = iPr; 3, R = Me, R′ = iPr; 4, R = H, R′ = tBu; 5, R = H, R′ = ...
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 ...
Photochemical reaction of Cp*Ir(CO)2 with C6F5X (X = CN, F) : formation of diiridium(II) complexes
Visible light irradiation of Cp*Ir(CO)2 (1) in pentafluorobenzontrile resulted in the formation of the two isomeric diiridium(II) complexes [Cp*Ir(μ-CO)(C6F4CN)]2 (3) and [Cp*Ir(CO)(C6F4CN)]2 (4), while the analogous reaction ...
