Application | diselenide is an important organic synthesis reagent and synthesis intermediate. For example: the application of dibenzyl diselenide in the synthesis of natural products; The practical application is very wide, the application of dibenzyl diselenide in the solid phase separation of light guide materials; Can accelerate the vulcanization of nitrile rubber; in cancer research, inhibit cancer. |
Use | inhibition of coking of RP-3 jet fuel by supercritical thermal cracking of dibenzyl diselenide. |
preparation | at present, the conventional synthesis method of dibenzyl diselenide is the reaction of chlorinated hydrocarbon with Grignard reagent; aromatic Aldehydes directly with hydrogen selenide gas. The disadvantages of these methods are that there are many steps, complicated operation, strong alkali participating in the reaction, low yield, and direct use of hydrogen selenide gas. |
