Enhanced Dihydrogen Activation by Mononuclear Iridium(II) Compounds: A Mechanistic Study
The organometallic chemistry of 4d and 5d transition metals has been vastly dominated by closed-shell states. The reactivity of their metalloradical species is though remarkable, albeit yet poorly understood and with limited mechanistic investigations available. In...![Asymmetric synthesis of dibenzo[b,d]azepines by Cu-catalyzed reductive or borylative cyclization](https://www.ciccartuja.es/wp-content/uploads/sites/4/2024/11/portada_revista_febrero-1080x675.jpg)
Asymmetric synthesis of dibenzo[b,d]azepines by Cu-catalyzed reductive or borylative cyclization
A copper-catalyzed asymmetric intramolecular reductive cyclization for the synthesis of dibenzo[b,d]azepines is described. Use of 2′-vinyl-biaryl-2-imines as substrates and in situ formed [CuI/(Ph-BPE)] as the catalyst enables the synthesis of 7-membered bridged...
Supported σ-Complexes of Li‒C Bonds from Coordination of Monomeric Molecules of LiCH3, LiCH2CH3 and LiC6H5 to MoMo Bonds
LiCH3 and LiCH2CH3 react with complex [Mo2(H)2(μ-AdDipp2)2(thf)2] (1 thf) with coordination of two molecules of LiCH2R (R=H,CH3) and formation of complexes [Mo2{μ-HLi(thf)CH2R}2(AdDipp2)2], 5 LiCH3 and 5 LiCH2CH3 , respectively (AdDipp2=HC(NDipp)2; Dipp=2,6-iPr2C6H3 ;...
Inhibition of the PP2A activity by the histone chaperone ANP32B is long-range allosterically regulated by respiratory cytochrome c
Repair of injured DNA relies on nucleosome dismantling by histone chaperones and de-phosphorylation events carried out by Protein Phosphatase 2A (PP2A). Typical histone chaperones are the Acidic leucine-rich Nuclear Phosphoprotein 32 family (ANP32) members, e.g....
