Silyl Radical Generation from Silylboronic Pinacol Esters through Substitution with Aminyl Radicals

Organic Letters, Год журнала: 2024, Номер 26(5), С. 1011 - 1016

Опубликована: Янв. 30, 2024

A novel strategy was developed to generate silyl radicals from silylboronic pinacol esters (SPEs) through nucleohomolytic substitution of boron with aminyl radicals. We successfully applied this obtain diverse organosilicon compounds using SPEs and N-nitrosamines under photoirradiation without any catalyst. The ability access offers a new perspective for chemists rapidly construct Si–X bonds.

Rongalite/Iodine-Mediated C(sp3)–H Bond Oximation and Thiomethylation Reaction of Methyl Ketones Using Copper Nitrate as the [NO] Reagent: Synthesis of Thiohydroximic Acids

Organic & Biomolecular Chemistry, Год журнала: 2024, Номер 22(37), С. 7623 - 7627

Опубликована: Янв. 1, 2024

In this work, a highly efficient rongalite/iodine-mediated oxime formation reaction for the preparation of thiohydroximic acids from methyl ketones by employing copper nitrate as [NO] reagent has been developed. Notably, participated both catalyst and mild oximation in transformation. This is facile, with broad substrate scope, especially fused ring skeleton substrates, heterocyclic acetyl-substituted natural products. Mechanistic studies revealed that might be converted into NO

Iron-Photocatalyzed Decarboxylative Alkylation of Carboxylic Acids with Morita–Baylis–Hillman Acetates

Organic Letters, Год журнала: 2024, Номер unknown

Опубликована: Дек. 27, 2024

We present an iron-photocatalyzed decarboxylative alkylation strategy involving carboxylic acids and Morita–Baylis–Hillman (MBH) acetates to synthesize E-type tri- tetrasubstituted alkenes with moderate excellent stereoselectivity (E/Z ratio up >19:1). This method is applicable a broad range of structurally diverse primary, secondary, tertiary alkyl acids, as well complex pharmaceutical natural achieving efficient various MBH under mild conditions (>60 examples, yields 96%). approach offers powerful for streamlined alkylation.

Nitrate Upcycling Mediated by Organonickel Catalysis

Abstract Nitrogen oxides (NO x ) are major environmental pollutants and to neutralize this long‐term threat, new catalytic methods needed. Although there biological denitrification processes involving four different enzymatic reactions convert nitrate 3 − into dinitrogen (N 2 ), it is unfortunately difficult apply in industry due the complexity of processes. In particular, functionalize because its chemical stability. Thus, no organometallic catalysis useful chemicals. Herein, we present a nickel pincer complex that effective as bifunctional catalyst stepwise deoxygenate NO by carbonylation further through C−N coupling. By using catalysis, salts can be selectively transformed various oximes (>20 substrates) with excellent conversion (>90 %). Here, demonstrate for first time highly inert ion functionalized produce chemicals organonickel catalysis. Our results show utilization (NCU) technology successful pathway restoration coupled value‐added generation.
