An efficient copper(I) iodide catalyzed synthesis of diaryl selenides through Cse bond formation using solvent acetonitrile as ligand

A wide range of diaryl selenides can be synthesized through CSe bond formation using readily available copper(I) iodide as catalyst under mild reaction conditions (82C) from aryl iodides and diphenyl diselenide. In this coupling reaction, solvent acetonitrile acts as ligand for copper(I) iodide and no external ligand is required. Less reactive aryl bromides also provide the di-aryl selenides in good isolated yields. Georg Thieme Verlag Stuttgart ? New York.

Trichloroisocyanuric Acid-Promoted Synthesis of Arylselenides and Aryltellurides from Diorganyl Dichalcogenides and Arylboronic Acids at Ambient Temperature

A transition-metal-free method for the synthesis of arylselenides and aryltellurides has been established based on the oxidative cross-coupling between diorganyl dichalcogenides and aryl boronic acids. With trichloroisocyanuric acid as an oxidant, the reaction proceeded smoothly to afford the desired products in 45–97% yields at ambient temperature. Three reaction reagents used in this method are stoichiometric and the oxidation by-product isocyanuric acid can be easily isolated and recovered. Besides of arylboronic acids, aryl trifluoroborates and aryl trihydroxyborates salts are also able to perform this transformation. (Figure presented.).

Harnessing SeN to develop novel fluorescent probes for visualizing the variation of endogenous hypobromous acid (HOBr) during the administration of an immunotherapeutic agent

By means of the formation of SeN, the ABT-Se and NDI-Se were developed to detect and visualize endogenous hypobromous acid (HOBr) in live cells. Specifically, the upregulation of HOBr was monitored by NDI-Se during the administration of an immunotherapeut

Method for preparing asymmetric organic selenium ether compounds through metal-free chemical oxidation method (by machine translation)

The method is mild in reaction condition, convenient to operate, high in 1 reaction condition, convenient 2 to operate, high in safety, wide in substrate range, high 2 - 8h in yield, particularly suitable for reaction of various poor 3 electric and sterically hindered arylboronic acid and diselenoxy ether, and capable of finishing most of the reaction 4h.

Syntheses of Thioethers and Selenide Ethers from Anilines

In this study, a general procedure was proposed for synthesizing thioethers and selenide ethers from anilines under solvent-free and transition-metal-free conditions. Thioethers were formed when anilines reacted with thiols under blue light-emitting-diode (LED) irradiation at room temperature without a photocatalyst. When reactions were performed using anilines and diselenides, the corresponding selenide ethers were obtained with satisfactory to excellent yields. The reaction was performed under photocatalyst-free and solvent-free conditions without blue LEDs. The advantages of this system include convenient operations, mild reaction conditions, satisfactory functional group tolerance, and late-stage selenylation of drug molecules.

Alternative Metal-Free Synthesis of Diorganoyl Selenides and Tellurides Mediated by Oxone

We herein describe an alternative metal-free methodology for the synthesis of diorganyl selenides and tellurides mediated by Oxone . The products were obtained in moderate to excellent yields by reactions of diorganyl diselenides or ditellurides with aryl boronic acids mediated by Oxone with use of EtOH as the solvent. The methodology is applicable to a broad scope of diorganyl dichalcogenides and aryl boronic acids containing electron-rich, electron-poor, and sterically hindered substituents.

Silver-Catalyzed Synthesis of Diaryl Selenides by Reaction of Diaryl Diselenides with Aryl Boronic Acids

We described herein our results on the silver-catalyzed synthesis of diaryl selenides via a cross-coupling reaction of diaryl diselenides with aryl boronic acids. The methodology is tolerant to electron-donor and electron-withdrawing groups at the substrates and the desired products were obtained in good to excellent yields.

Glycerol as a recyclable solvent for copper-catalyzed cross-coupling reactions of diaryl diselenides with aryl boronic acids

We describe herein the use of glycerol as the solvent in the copper-catalyzed cross-coupling reaction of diaryl diselenides with arylboronic acids using CuI and DMSO as additive. This cross-coupling reaction was performed with diaryl diselenides and arylboronic acids bearing electron-withdrawing and electron-donating groups, affording the corresponding diaryl selenides in good to excellent yields. The glycerol-CuI mixture can be directly reused for further cross-coupling reactions.

Synthesis of diaryl selenides using electrophilic selenium species and nucleophilic boron reagents in ionic liquids

We described herein the use of imidazolium ionic liquids [bmim]PF 6 and [bmim]BF4 in the selective, metal and catalyst-free synthesis of unsymmetrical diaryl selenides by electrophilic substitution in arylboron reagents with arylselenium halides (Cl and Br) at room temperature. This is a general substitution reaction and it was performed with arylboronic acids or potassium aryltrifluoroborates bearing electron-withdrawing or electron-donating groups, affording the corresponding diaryl selenides in good to excellent yields. The ionic liquid [bmim][PF6] was easily recovered and utilized for further substitution reactions.
