Xu, Liangxuan published the artcileMomentary click nitrile synthesis enabled by an aminoazanium reagent, Computed Properties of 1205-17-0, the main research area is nitrile preparation selective Schmidt reaction aminoazanium reagent.

Momentary and selective Schmidt-type nitrile synthesis was reported. The success of this achievement was ascribed to the employment of the stable and robust aminoazanium reagent H2N-DABCO. A broad range of functionalized aldehydes were efficiently converted to nitriles within 5 min at room temperature in air. The robustness and speed of the protocol allow the CHO group to be regarded as a CN equivalent in organic synthesis. Moreover, the synthetic advantage of this developed protocol is further highlighted via the direct cyanation of a diversity of aldehyde precursors (carboxylic acids, aromatics, aryl halides, alkenes and alkynes) in a cyanide-free process. Addnl., this protocol can not only be used for rapid access to a wide range of ligands and material precursors, but it can also be used in the late-stage modification of complex bioactive mols.

Kawasaki, Tairin published the artcileDehydrogenative Coupling of Benzylic and Aldehydic C-H Bonds, Application In Synthesis of 1205-17-0, the main research area is alkylarene aldehyde iridium nickel catalyst dehydrogenative cross coupling; aryl ketone preparation; methylamide aldehyde iridium nickel catalyst dehydrogenative cross coupling; amino ketone preparation.

A photoinduced dehydrogenative coupling reaction between benzylic and aldehydic C-H bonds was reported. When a solution of an alkylbenzene and an aldehyde in Et acetate was irradiated with visible light in the presence of iridium and nickel catalysts, a coupled α-aryl ketone was formed with evolution of dihydrogen. An analogous C-C bond forming reaction occurs between a C-H bond next to the nitrogen of an N-methylamide and an aldehydic C-H bond to produce an α-amino ketone. These reactions provide a straightforward pathway from readily available materials leading to valued structural motifs of pharmacol. relevance.

Hoshimoto, Yoichi published the artcileMain-Group-Catalyzed Reductive Alkylation of Multiply Substituted Amines with Aldehydes Using H2, Product Details of C11H12O3, the main research area is dichlorophenyl tetrafluorophenyl boron frustrated Lewis pair catalyzed reductive alkylation; main group catalyzed reductive alkylation multiply substituted amine aldehyde; imine preparation frustrated Lewis pair catalyzed hydrogenation; isoindolinone aminophthalic anhydride preparation; crystal mol structure dichlorophenyl tetrafluorophenyl boron frustrated Lewis pair; aminonitrophenoxy benzylaniline preparation crystal mol structure; benzylamino isobenzofurandione preparation crystal mol structure; benzylaminophthalic acid preparation crystal mol structure.

Given the growing demand for green and sustainable chem. processes, the catalytic reductive alkylation of amines with main-group catalysts of low toxicity and mol. hydrogen as the reductant would be an ideal method to functionalize amines. However, such a process remains challenging. Herein, a novel reductive alkylation system using H2 is presented, which proceeds via a tandem reaction that involves the B(2,6-Cl2C6H3)(p-HC6F4)2-catalyzed formation of an imine and the subsequent hydrogenation of this imine catalyzed by a frustrated Lewis pair (FLP). This reductive alkylation reaction generates H2O as the sole byproduct and directly functionalizes amines that bear a remarkably wide range of substituents including carboxyl, hydroxyl, addnl. amino, primary amide, and primary sulfonamide groups. The synthesis of isoindolinones and aminophthalic anhydrides has also been achieved by a one-pot process that consists of a combination of the present reductive alkylation with an intramol. amidation and intramol. dehydration reactions, resp. The reaction showed a zeroth-order and a first-order dependence on the concentration of an imine intermediate and B(2,6-Cl2C6H3)(p-HC6F4)2, resp. In addition, the reaction progress was significantly affected by the concentration of H2. These results suggest a possible mechanism in which the heterolysis of H2 is facilitated by the FLP comprising THF and B(2,6-Cl2C6H3)(p-HC6F4)2.

Applying these catalysts, structurally diverse benzylic, aliphatic and heterocyclic primary, secondary and tertiary amines, including pharmaceutically relevant products, starting from inexpensive and easily accessible carbonyl compounds with ammonia, nitro compounds or amines and mol. hydrogen were synthesized. To prepare this cobalt-based catalyst took 26 h, and the reported catalytic reductive amination reactions could be carried out within 18-28 h.
