Spotlight on the Nucleotide: Solid‐State NMR for the Investigation of ATP Hydrolysis in the ATPase SmsC

Chemistry – A European Journal, EarlyView.
Nucleotide‐detected solid‐state NMR has been applied to probe nucleotide conformations and dynamics during ATP hydrolysis using the dimeric P‐loop ATPase SmsC as a model protein. The different stages of ATP hydrolysis have been mimicked by ATP analogues for which different degrees of conformational heterogeneity have been observed. ABSTRACT Solid‐state

Routes to Cyclobutadiene and Cycloallyl Pt(II) Complexes: Dicationic Bis(Alkyne) Species as Intermediates

Chemistry – A European Journal, EarlyView.
This work demonstrates the synthesis of cationic Pt(II) η3‐cycloallyl complexes, and experimental and computational studies show a ligand bite‐angle dependence of their formation rates. The reactivity of these complexes with Brønsted acids was investigated, leading to the formation of cationic and dicationic Pt(II) η4‐cyclobutadiene complexes ...

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate

Chemistry – A European Journal, EarlyView.
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Stereoretentive Nucleophilic Aromatic Substitution Accesses Atropisomeric 4‐Amino‐N‐Arylquinolinium Salts

Chemistry – A European Journal, EarlyView.
Quinolin‐4‐ones were converted to chloroquinolinium salts, allowing formation of axially chiral aminoquinolinium salts via an enantioretentive SNAr reaction with a variety of amine nucleophiles. The salts have a high rotational barrier, with a racemization half‐life of ∼1000s of years.

Azidophosphonamido Rhodium(I) and Iridium(I) Complexes: Synthesis, Properties, and Linkage Isomerism

Chemistry – A European Journal, EarlyView.
A family of azidophosphonamido ligands and their corresponding rhodium(I) and iridium(I) complexes were synthesized. The rich reaction chemistry of these species revealed unusual linkage isomerization processes and bonding motifs. M = Rh, Ir; Mes = 2,4,6‐Me3C6H2. ABSTRACT A series of azidophosphonamido rhodium(I) and iridium(I) complexes ([iPr2P(N3R)NR]
