Redox-Neutral Synthesis of Selenoesters by Oxyarylation of Selenoalkynes under Mild Conditions

An approach for the mild synthesis of selenoesters starting from selenoalkynes through an acid-catalyzed, redox-neutral oxyarylation reaction is reported. Br?nsted acid activation of a selenoalkyne leads to a selenium-stabilized vinyl cation, which is cap

Mechanochemical Synthesis of Active Magnetite Nanoparticles Supported on Charcoal for Facile Synthesis of Alkynyl Selenides by C?H Activation

Magnetite (Fe3O4) nanoparticles supported on charcoal, graphene, or SBA-15 were prepared by a simple solid-state grinding technique and subsequent thermal treatment. The Fe3O4 nanoparticles supported on activated charcoal exhibited high catalytic activity and furnished good yields of the alkynyl selenide product in the cross-coupling reaction of diphenyl diselenide and alkynes through activation of C?H and Se?Se bonds under ecofriendly conditions, surpassing traditional copper-based catalysts to effect the same organic transformation.

A General and highly efficient protocol for the synthesis of chalcogenoacetylenes by copper(I)-terpyridine catalyst

A highly efficient copper-catalyzed Csp-X (X = S, Se, Te) bond-forming reaction of terminal alkynes and diorganyl dichalcogenides has been developed. This transformation was realized through the use of copper(I) iodide as a catalyst, 4′-(4-meth

Cryptand-22 as an efficient ligand for the copper-catalyzed cross-coupling reaction of diorgano dichalcogenides with terminal alkynes leading to the synthesis of alkynyl chalcogenides

A general and efficient method for the cross-coupling reaction of diorgano dichalcogenides with terminal alkynes using copper iodide/cryptand-22 (CuI/C22) has been developed. This protocol gave alkynyl chalcogenides in moderate to excellent yields in the

A simple and effective approach to the synthesis of alkynyl selenides from terminal alkynes

Alkynyl selenides were prepared under very mild conditions by reacting terminal alkynes with respective diorganic diselenides in the presence of potassium t-butoxide. The advantages of this protocol include the use of readily available substrates and reag

1-Iodo-1-selenoalkenes as versatile alkene 1,1-dianion equivalents. Novel connective approach towards the tetrahydropyran subunit of polycavernoside A

syn-Hydroalumination of 2,4,6-triisopropylphenylselanyl-1-alkynes with DIBAL-H followed by Al/I exchange with I2 afforded exclusively (E)-1-iodo-1-selenoalkenes in good yields. 1-Iodo-1-selenopropene 10 proved to be a convenient 1,1 dianion equivalent, leading to the stereodivergent synthesis of allylsilanes (Z)-6 and (E)-6. Adduct 3, an intermediate in the synthesis of the tetrahydropyran subunit of polycavernoside A, was efficiently synthesised from allylsilane (Z)-6 and aldehyde 7 via an intramolecular Sakurai cyclisation.

A novel and highly efficient synthetic route to unsymmetrical organoselenides using cesium bases

A new and convenient one-pot method for the preparation of unsymmetrical selenides has been developed. In the presence of cesium hydroxide, molecular sieves, and DMF, benzeneselenol undergoes direct alkylation with various alkyl halides for the synthesis of alkyl phenyl selenides in moderate to excellent yields. Another method to prepare unsymmetrical organoselenides was also completed by coupling terminal alkynes with benzeneselenyl bromide. As an application, the synthesis of a selenopeptide was also accomplished. Furthermore, this methodology was extended to the synthesis of an organoselenide on solid support.

Short and efficient preparation of alkynyl selenides, sulfides and tellurides from terminal alkynes

Diphenyl diselenide reacts with terminal alkynes at room temperature in DMSO in the presence of catalytic amounts of copper iodide to give good to excellent yields of alkynyl phenyl selenides. The reaction occurs under neutral conditions and the solvent a

Hydroalumination and bromination of 1-(phenylselenyl)- 1-alkynes
