Vandavasi, Jaya Kishore published the artcileA Nickel-Catalyzed Carbonyl-Heck Reaction, COA of Formula: C11H12O3, the main research area is Heck organotriflate aldehyde nickel catalyst triphos ligand amine base; Heck reactions; acylation; cross-coupling; ketones; nickel.

The use of transition-metal catalysis to enable the coupling of readily available organic mols. has greatly enhanced the ability of chemists to access complex chem. structures. In this work, an intermol. coupling reaction that unites organotriflates and aldehydes is presented. A unique catalyst system is identified to enable this reaction, featuring a Ni0 precatalyst, a tridentate Triphos ligand, and a bulky amine base. This transformation provides access to a variety of ketone-containing products without the selectivity- and reactivity-related challenges associated with more traditional Friedel-Crafts reactions. A Heck-type mechanism is postulated, wherein the π bond of the aldehyde takes the role of the olefin in the insertion/elimination steps.

Liang, Shengzong published the artcileSynthesis of Alkyl Halides from Aldehydes via Deformylative Halogenation, COA of Formula: C11H12O3, the main research area is alkyl halide synthesis aldehyde deformylative halogenation.

An unprecedented deformylative halogenation of aldehydes to alkyl halides is presented. Under oxidative conditions, 1,4-dihydropyridine (DHP), derived from an aldehyde, generated a C(sp3) radical that coupled with a halogen radical that was generated from inexpensive and atom-economical halogen sources (NaBr, NaI, or HCl), to yield an alkyl halide. Because of the mild conditions, a wide range of functional groups were tolerated, and excellent site selectivity was achieved.

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.
