Synthetic method of diselenide compound
-
Paragraph 0029-0046, (2021/03/13)
The invention relates to a synthetic method of a diselenide compound, which comprises the following steps: putting arylboronic acid or derivatives thereof, elemental selenium, trimethylsilyl cyanide and an organic solvent into a reaction container to obtain a mixed solution, heating the mixed solution to 110-140 DEG C, stirring and reacting at the temperature for 18-30 hours to obtain a reaction solution, and carrying out aftertreatment to obtain a diselenide compound, wherein the ratio of the arylboronic acid or the derivative of the arylboronic acid to the elemental selenium to the trimethylsilyl cyanide is (6-10): (9-11): 1, wherein the dosage of the organic solvent is 4-6ml/mmol based on the molar weight of the arylboronic acid or the derivative thereof. The method has the following beneficial effects: 1, elemental selenium is adopted to replace a metal catalyst, metal is not needed for catalytic reaction, and the product is relatively environment-friendly; 2, the reaction conditions are mild, and the functional group tolerance is good; 3, a non-aryl phenol compound is used, so that the method is relatively environment-friendly; and 4, the yield is high.

The rearrangement of selenium ylides is even today almost unexplored, although it would provide access to important organoselenium compounds with broad downstream applications. In this report, the first systematic study of sigmatropic rearrangement reactions of selenium ylides using a simple rhodium catalyst with catalyst loadings as low as 0.01 mol % is described. Selenium oxide pyrolysis of the rearrangement products gives access to important 1,1-disubstituted butadienes.

1,2-Bis[3,5-bis(trifluoromethyl)phenyl]diselane-catalyzed oxidation of cyclohexene by hydrogen peroxide affords a quick, clean and practical access to the important compound trans-1,2-cyclohexanediol under mild conditions. The highly atom-economic properties, clean procedures, high reaction concentration, short reaction time, mild conditions and eco-friendly, recyclable and low loading catalysts facilitate this methodology for possible future practical industrial production.
