Realistic Energy Surfaces for Real‐World Systems: An IMOMO CCSD(T):DFT Scheme for Rhodium‐Catalyzed Hydroformylation with the 6‐DPPon Ligand
Authors: Gellrich Urs , Himmel Daniel , Meuwly Markus , Breit Bernhard
Published: October 2013

The hydroformylation of terminal alkenes is one of the most important homogeneously catalyzed processes in industry, and the atomistic understanding of this reaction has attracted enormous interest in the past. Herein, the whole catalytic cycle for rhodium‐catalyzed hydroformylation with the 6‐diphenylphosphinopyridine‐(2H)‐1‐one (6‐DPPon) ligand 1 was studied. This catalytic transformation is challenging to describe computationally, since two requirements must be met: 1) changes in the hydrogen‐bond network must be modeled accurately and 2) bond‐formation/bond‐breaking processes in the coordination sphere of the rhodium center must be calculated accurately. Depending on the functionals used (BP86, B3LYP), the results were found to differ strongly. Therefore, the complete cycle was calculated by using highly accurate CCSD(T) computations for a PH3 model ligand. By applying an integrated molecular orbital plus molecular orbital (IMOMO) method consisting of CCSD(T) as high level and DFT as low‐level method, excellent agreement between the two functionals was achieved. To further test the reliability of the calculations, the energetic‐span model was used to compare experimentally derived and computed activation barriers. The accuracy of the new IMOMO method apparently makes it possible to predict the catalytic potential of real‐world systems.
The Synthesis of Methylated, Phosphorylated, and Phosphonated 3′‐Aminoacyl‐tRNASec Mimics

Published: October 2013

The twenty first amino acid, selenocysteine (Sec), is the only amino acid that is synthesized on its cognate transfer RNA (tRNASec) in all domains of life. The multistep pathway involves O‐phosphoseryl‐tRNA:selenocysteinyl‐tRNA synthase (SepSecS), an enzyme that catalyzes the terminal chemical reaction during which the phosphoseryl–tRNASec intermediate is converted into selenocysteinyl‐tRNASec. The SepSecS architecture and the mode of tRNASec recognition have been recently determined at atomic resolution. The crystal structure provided valuable insights that gave rise to mechanistic proposals that could not be validated because of the lack of appropriate molecular probes. To further improve our understanding of the mechanism of the biosynthesis of selenocysteine in general and the mechanism of SepSecS in particular, stable tRNASec substrates carrying aminoacyl moieties that mimic particular reaction intermediates are needed. Here, we report on the accurate synthesis of methylated, phosphorylated, and phosphonated serinyl‐derived tRNASec mimics that contain a hydrolysis‐resistant ribose 3′‐amide linkage instead of the natural ester bond. The procedures introduced allow for efficient site‐specific methylation and/or phosphorylation directly on the solid support utilized in the automated RNA synthesis. For the preparation of (S)‐2‐amino‐4‐phosphonobutyric acid–oligoribonucleotide conjugates, a separate solid support was generated. Furthermore, we developed a three‐strand enzymatic ligation protocol to obtain the corresponding full‐length tRNASec derivatives. Finally, we developed an electrophoretic mobility shift assay (EMSA) for rapid, qualitative characterization of the SepSecS‐tRNA interactions. The novel tRNASec mimics are promising candidates for further elucidation of the biosynthesis of selenocysteine by X‐ray crystallography and other biochemical approaches, and could be attractive for similar studies on other tRNA‐dependent enzymes.
Arene CH Amination at Nickel in Terphenyl–Diphosphine Complexes with Labile Metal–Arene Interactions
Authors: Herbert David E. , Lara Nadia C. , Agapie Theodor
Published: October 2013

The meta‐terphenyl diphosphine, m‐P2, 1, was utilized to support Ni centers in the oxidation states 0, I, and II. A series of complexes bearing different substituents or ligands at Ni was prepared to investigate the dependence of metal–arene interactions on oxidation state and substitution at the metal center. Complex (m‐P2)Ni (2) shows strong Ni0–arene interactions involving the central arene ring of the terphenyl ligand both in solution and the solid state. These interactions are significantly less pronounced in Ni0 complexes bearing L‐type ligands (2‐L: L=CH3CN, CO, Ph2CN2), NiIX complexes (3‐X: X=Cl, BF4, N3, N3B(C6F5)3), and [(m‐P2)NiIICl2] (4). Complex 2 reacts with substrates, such as diphenyldiazoalkane, sulfur ylides (Ph2SCH2), organoazides (RN3: R=para‐C6H4OMe, para‐C6H4CF3, 1‐adamantyl), and N2O with the locus of observed reactivity dependent on the nature of the substrate. These reactions led to isolation of an η1‐diphenyldiazoalkane adduct (2‐Ph2CN2), methylidene insertion into a NiP bond followed by rearrangement of a nickel‐bound phosphorus ylide (5) to a benzylphosphine (6), Staudinger oxidation of the phosphine arms, and metal‐mediated nitrene insertion into an arene CH bond of 1, all derived from the same compound (2). Hydrogen‐atom abstraction from a NiI–amide (9) and the resulting nitrene transfer supports the viability of Ni–imide intermediates in the reaction of 1 with 1‐azido‐arenes.
