Aqueous phase preparation method of dialkyl diselenide ether compound

The method comprises the following steps: taking the compound represented by the formula (II) as a reaction raw material and I as a reaction raw material, and taking water or ethanol as a solvent under Se 40 - 75 °C conditions to obtain the reaction liquid to obtain the dialkyl diselenium ether compound shown in the formula (II KOH). The reaction is short in reaction time, does not need a metal catalyst, uses water as a solvent, and belongs to green and environment-friendly reaction. Economy, high efficiency, green, environmental protection.

Synthesis of selenated tetracyclic indoloazulenesviaiodine and diorganyl diselenides

Herein, we report an efficient protocol for the synthesis of selenated tetracyclic indoloazulenes. The reaction of diorganyl diselenides with molecular iodine in dichloromethane leads to thein situformation of organo selenenyl iodide. The synthesis of selenylated tetracyclic indoloazulenes through intramolecular cascade cyclization has been achievedviaorgano selenenyl iodide and bisindole at room temperature under metal-free conditions in good yields. All compounds were fully characterized by the FT-IR, HRMS, and1H,13C and77Se NMR spectral data.

Silicon-mediated synthesis of selenoaldehydes and selenoacylsilanes and their hetero diels-alder reactions

Bis(trimethylsilyl)selenide (HMDSS) reacts efficiently with aldehydes in the presence of CoCl2.6H2O to afford selenoaldehydes, which are trapped as Diels-Alder adducts by different dienes. The reaction can be applied to acylsilanes, to afford selenoacylsilanes, isolated as their cycloadducts.

A synthetic method for diselenides under phase-transfer conditions

Diselenides were easily prepared in high yields by the alkylation of sodium diselenide on halides in water under phase-transfer conditions.

A NEW REACTION OF DIALLYL SELENIDE, LEADING TO 1,3,5-HEXATRIENE

In the highly basic potassium hydroxide-DMSO system at 50-80 deg C diallyl selenide is converted into 1,3,5-hexatriene.Alkyl allyl selenides do not enter into this reaction but undergo isomerization to alkyl 1-propenyl selenides.

(1)H and (13)C NMR Studies on the Positional Isomers of Methyl Selenalaurate and Telluralaurate

A report is given of the (1)H and (13)C NMR spectra of a series of methyl selenalaurates and telluralaurates in which successive methylene groups have been replaced by a selenium or a tellurium atom.The effect on contiguous carbons is a marked upfield shift (shielding) while the protons attached to these carbons are deshielded.The β-and γ protons are weakly deshielded.
