Synthesis of terpenyl selenides derived from limonene, menthol, caranol, and myrtanol is described. Three methodologies for the synthesis of terpenyl selenonium salts are compared. The results of selenium-mediated epoxidation through the use of isoselenocineole derived from limonene and methyl terpenyl, phenyl terpenyl, diterpenyl selenides, and selenonium salts are presented. The influence of solvent
The first regioselective selenocarbonylation of alkenes is reported. This general protocol provides a variety of branched and linear selenoesters with wide functional group compatibility and tunable regioselectivity.
