Metal-free sulfonylation of arenes with: N -fluorobenzenesulfonimide via cleavage of S-N bonds: expeditious synthesis of diarylsulfones

A novel metal-free sulfonylation of arenes with N-fluorobenzenesulfonimide (NFSI) toward the synthesis of diarylsulfones has been developed. The reaction represents a rare example of sulfonylation reaction using NFSI as an efficient sulfonyl donor and the first example of acid-mediated sulfonylation of unactivated arenes with NFSI via selective cleavage of S-N bonds. This protocol provides a concise approach for the construction of pharmaceutically and biologically important diarylsulfones. Applications in the functionalization of natural products (e.g., β-estradiol) and in the synthesis of a key intermediate to an inhibitor of farnesyl-protein transferase, as well as in the gram-scale synthesis of the EPAC2 antagonist, are demonstrated.

Electrochemistry Enabled Nickel-Catalyzed Selective C?S Bond Coupling Reaction

This work describes an electrochemical enabled nickel-catalyzed chemoselective C?S bond coupling protocol for the production of aryl sulfides and sulfones. By simply switching the nickel catalysts and electrodes, this electrochemical C?S bond coupling has demonstrated excellent redox activity, scalability and sustainability. Furthermore, the mechanism for this electrochemical cross-coupling reaction has been investigated.

A Copper(I)-Catalyzed Sulfonylative Hiyama Cross-Coupling

An air-tolerant Cu-catalyzed sulfonylative Hiyama cross-coupling reaction enabling the formation of diaryl sulfones is described. Starting from aryl silanes, DABSO and aryliodides, the reaction tolerates a large variety of polar functional groups (amines, ketones, esters, aldehydes). Control experiments coupled with DFT calculations shed light on the mechanism, characterized by the formation of a Cu(I)-sulfinate intermediate via fast insertion of a SO2 molecule.

Pd/NHC-catalyzed arylsulfonylation of boronic acids: A general and direct protocol to access diarylsulfones

For the first time, robust NHC-Pd complexes have been demonstrated as highly efficient catalysts in the direct arylsulfonylation of boronic acids. Remarkably, a broad number of diaryliodonium salts as powerful electrophilic arylation reagents are well compatible to form functional ortho-substituted diarylsulfones in satisfactory yields. Owing to the stronger σ-donor and weaker π-acceptor properties, the acenaphthoimidazolylidene ligands exhibit higher catalytic activities towards this challenging one-step arylsulfonylation reaction.

On the important transition of sugar-based surfactant as a microreactor for C-S coupling in water: From micelle to vesicle

A reversible, temperature-induced micelle-to-vesicle transition of a sugar-based pseudogemini surfactant (C11D12) was employed for copper-catalyzed C-S coupling in water. The phase behavior and morphology of the C11D12 aqueous solution were investigated by DLS and cryo-TEM. The aggregates undergo a series of transitions upon increasing the temperature: spherical micelles were initially transformed into large vesicles, but they eventually transformed into smaller vesicles. The vesicular catalytic protocol accommodates an excellent substrate scope with moderate to high yields. The mechanisms of temperature-induced aggregate transition and vesicular catalysis were elucidated by experimental results and DFT calculations. It was revealed that the charge layer of the vesicle grants stronger nucleophilicity to the PhSO2-Cu-D12Ga intermediate. Furthermore, the aqueous reaction medium can be recycled and reused several times after easily separating the precipitated product.

Interfacing sugar-based surfactant micelles and Cu nanoparticles: A nanoreactor for C-S coupling reactions in water

A simple and sustainable synergistic catalytic protocol by interfacing nanomicelles and metal nanoparticles (MNPs) is reported for C-S coupling reactions in water. The sugar-based surfactant GluM was synthesized by introducing a PEG chain to stabilize MNPs and self-assembled to form nanomicelles. Cu2O nanoparticles were generated via in situ reduction of copper salt in an aqueous solution of the sugar-based surfactant. The nature of the interaction between nanomicelles and Cu2O nanoparticles was revealed by XPS, XRD, in situ IR, TEM, and 1H NMR. A broad substrate scope with moderate to excellent yields was documented and the recycling of the GluM/Cu aqueous mixture was surprising.

Silyloxymethanesulfinate as a sulfoxylate equivalent for the modular synthesis of sulfones and sulfonyl derivatives

An efficient protocol for the modular synthesis of sulfones and sulfonyl derivatives has been developed utilizing sodium tert-butyldimethylsilyloxymethanesulfinate (TBSOMS-Na) as a sulfoxylate (SO22-) equivalent. TBSOMS-Na, easily prepared from the commercial reagents Rongalite and TBSCl, serves as a potent nucleophile in S-alkylation and Cu-catalyzed S-arylation reactions with alkyl and aryl electrophiles. The sulfone products thus obtained can undergo the second bond formation at the sulfur center with various electrophiles without a separate unmasking step to afford sulfones and sulfonyl derivatives such as sulfonamides and sulfonyl fluorides.

Regiospecific Cleavage of S-N Bonds in Sulfonyl Azides: Sulfonyl Donors

Sulfonyl azides have been widely used as sulfonamido, diazo, and azido donors, as well as all-nitrogen 1,3-dipoles donors in synthetic chemistry. Here, the sulfonyl azides were used as efficient sulfonyl donors, which is very unusual. Trifluoromethanesulfonic acid-induced formation of the sulfonyl cation reactive species from sulfonyl azides was developed and used for the first time to couple various inactivated arenes to prepare sulfones at ambient temperature.
