Zhang, Xinyu published the artcileUse of trifluoroacetaldehyde N-tfsylhydrazone as a trifluorodiazoethane surrogate and its synthetic applications, Formula: C7H6N2, the main research area is thiol trifluorodiazoethane iron porphyrin catalyst difluoroalkenylation; alc trifluorodiazoethane iron porphyrin catalyst difluoroalkenylation; amine trifluorodiazoethane iron porphyrin catalyst difluoroalkenylation; unsaturated compound trifluorodiazoethane iron porphyrin catalyst Doyle Kirmse reaction; alkene trifluorodiazoethane iron porphyrin catalyst diastereoselective cyclopropanation.

The development of trifluoroacetaldehyde N-tfsylhydrazone (TFHZ-Tfs) as a CF3CHN2 surrogate, which was capable of generating CF3CHN2 in-situ under basic conditions was reported. The reaction conditions employed in this chem. enabled a difluoroalkenylation of X-H bonds (X = N, O, S, Se), affording a wide range of heteroatom-substituted gem-difluoroalkenes, along with Doyle-Kirmse rearrangements and trifluoromethylcyclopropanation reactions, with superior outcomes to approaches using pre-formed CF3CHN2. Given the importance of generally applicable fluorination methodologies, the use of TFHZ-Tfs thus creates opportunities across organic and medicinal chem., by enabling the wider exploration of the reactivity of trifluorodiazoethane.

Zhao, Yiyong published the artcileSO2F2-Promoted Dehydration of Aldoximes: A Rapid and Simple Access to Nitriles, Name: Picolinonitrile, the main research area is nitrile preparation; aldoxime dehydration.

A rapid, simple and mild process for the dehydration of aldoximes RCH=NOH (R = benzyl, 4-fluorophenyl, naphth-1-yl, pyridin-2-yl, etc.) to give the corresponding nitriles RCN, which utilizes SO2F2 as an efficient reagent, has been developed. A variety of (hetero)arene, alkene, alkyne and aliphatic aldoximes proceeded with high efficiency to afford nitriles in excellent to quant. yields with great functional group compatibilities in acetonitrile under ambient conditions. Moreover, the eco-friendly conditions of SO2F2/Na2CO3/aqueous methanol were suitable for converting nitrobenzaldoximes R1C6H4CH=NOH (R1 = 2-nitro, 3-nitro, 4-nitro) into nitrobenzonitriles R1C6H4CN.

Pandey, Vipin K. published the artcileSilver-Catalyzed Hydroboration of C-X (X = C, O, N) Multiple Bonds, Synthetic Route of 100-70-9, the main research area is silver catalyst hydroboration carbon oxygen nitrogen multiple bond.

AgSbF6 was developed as an effective catalyst for the hydroboration of various unsaturated functionalities (nitriles, alkenes, and aldehydes). This atom-economic chemoselective protocol works effectively under low catalyst loading, base- and solvent-free moderate conditions. Importantly, this process shows excellent functional group tolerance and compatibility with structurally and electronically diverse substrates (>50 examples). Mechanistic investigations revealed that the reaction proceeds via a radical pathway. Further, the obtained N,N-diborylamines were showcased to be useful precursors for amide synthesis.

Liu, Lin published the artcileCopper-Catalyzed Intermolecular Enantioselective Radical Oxidative C(sp3)-H/C(sp)-H Cross-Coupling with Rationally Designed Oxazoline-Derived N,N,P(O)-Ligands, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is cycloalkene alkyne copper catalyst regioselective enantioselective oxidative cross coupling; cycloalkenyl alkyne preparation; alkyne aryl alkene copper catalyst enantioselective oxidative cross coupling; aryl alkyne preparation regioselective; alkynylation; anionic N,N,P(O)-ligands; copper catalysis; oxidative cross-coupling; radical asymmetric chemistry.

Here, a copper-catalyzed asym. C(sp3)-C(sp) cross-coupling of (hetero)benzylic and (cyclic)allylic C-H bonds with terminal alkynes that occurs with high to excellent enantioselectivity was reported. Critical to the success is the rational design of chiral oxazoline-derived N,N,P(O)-ligands that not only tolerate the strong oxidative conditions which were requisite for intermol. hydrogen atom abstraction (HAA) processes but also induce the challenging enantiocontrol. Direct access to a range of synthetically useful chiral benzylic alkynes and 1,4-enynes, high site-selectivity among similar C(sp3)-H bonds, and facile synthesis of enantioenriched medicinally relevant compounds make this approach very attractive.
