Chen, Ying;Xu, Lanting;Jiang, Yongwen;Ma, Dawei research published 《 Assembly of α-(Hetero)aryl Nitriles via Copper-Catalyzed Coupling Reactions with (Hetero)aryl Chlorides and Bromides》, the research content is summarized as follows. α-(Hetero)aryl nitriles are important structural motifs for pharmaceutical design. The known methods for direct synthesis of these compounds via coupling with (hetero)aryl halides suffer from narrow reaction scope. Herein, we report that the combination of copper salts and oxalic diamides enables the coupling of a variety of (hetero)aryl halides (Cl, Br) and Et cyanoacetate under mild conditions, affording α-(hetero)arylacetonitriles via one-pot decarboxylation. Addnl., the CuBr/oxalic diamide catalyzed coupling of (hetero)aryl bromides with α-alkyl-substituted Et cyanoacetates proceeds smoothly at 60°C, leading to the formation of α-alkyl (hetero)arylacetonitriles after decarboxylation. The method features a general substrate scope and is compatible with various functionalities and heteroaryls. Thus, e.g., 4-chloroanisole + Et cyanoacetate → 2-(4-methoxyphenyl)acetonitrile (up to 80%).

Cho, Yae In;Durgaprasad, Gummadi;Rose, Michael J. research published 《 CNS and CNP Iron(II) Mono-Iron Hydrogenase (Hmd) Mimics: Role of Deprotonated Methylene(acyl) and the trans-Acyl Site in H₂ Heterolysis》, the research content is summarized as follows. The authors report synthesis and H₂ activation involving model complexes of monoiron hydrogenase (Hmd) derived from acyl-containing pincer ligand precursors bearing thioether (CNS^Pre) or phosphine (CNP^Pre) donor sets. Both complexes feature pseudo-octahedral iron(II) dicarbonyl units. While the CNS pincer adopts the expected mer-CNS (pincer) geometry, the CNP ligand unexpectedly adopts the fac-CNP coordination geometry. Both complexes exhibit an acidic methylene C-H bond (reversibly de/protonated by a bulky phenolate), which affords a dearomatized pyridinate-bound intermediate. Notably, dearomatization of Fe-CNS also results in deligation of the thioether sulfur donor, generating an open coordination site trans from the acyl unit. In contrast, Fe-CNP maintains a CO ligand trans from the acyl site both in the parent and dearomatized complexes (-PPh₂ donor is cis to acyl). The dearomatized mer-Fe-CNS was competent for H₂ activation (5 atm D_2(g) plus phenolate as base), which is attributed to both the basic site on the ligand framework and the open coordination site trans to the acyl donor. In contrast, the dearomatized fac-Fe-CNP was not competent for H₂ activation, which is ascribed to the blocked coordination site trans from acyl (occupied by CO ligand). These results highlight the importance of both (i) the open coordination site trans to the organometallic acyl donor, and (ii) a pendant base in the enzyme active site.
