| Abstract: | In the presence of BiCl 3 Al, the reaction of diselenide and allylic or benzylic bromide gives selenides. Two kinds of useful selenoxide reagents are synthesized via the oxidation of selenides by CAN under the condition of phase transfer catalysis. And a new class of selenoxide based oxidant selenoxide sulfonic acid salts are readily prepared by simple addition of p toluenesulfonic acid to the solution of selenoxides. |
