In the presence of BiCl3/Al or BiCl3/Fe, in THF-H2O, allylic (benzylic) bromides or α-bromoketones react with diorganyl diselenides to give allylic (benzylic) selenides orα-organylselenocarbonyl compounds respective...In the presence of BiCl3/Al or BiCl3/Fe, in THF-H2O, allylic (benzylic) bromides or α-bromoketones react with diorganyl diselenides to give allylic (benzylic) selenides orα-organylselenocarbonyl compounds respectively in moderate to good yields.展开更多
An iridium-catalyzed allylic substitution of sodium phenyl selenide with unsymmetrical allyl carbonates was accomplished, which produced the linear allyl phenyl selenides in 38%--74% yields. An asymmetric irid- ium-ca...An iridium-catalyzed allylic substitution of sodium phenyl selenide with unsymmetrical allyl carbonates was accomplished, which produced the linear allyl phenyl selenides in 38%--74% yields. An asymmetric irid- ium-catalyzed allylation of sodium phenyl selenide was presented as well.展开更多
Allyl and benzyl selenides were synthesized via reactions of allyl and benzyl bromides and diselenides promoted by Sm/Sb-Cl3 system in aqueous media in moderate to good yields.
