Sodium and potassium alkane[arene]selenolates have been efficiently prepared from the corresponding diselenides using sodium or potassium hydrides in dimethylformamide or tetrahydrofuran. The reaction cannot be extended for the production of their lithium analogues nor for sodium and potassium phenylmethaneselenolates.

Selenones are prepared by oxidation of selenides by hydrogen peroxide-benzeneseleninic acid. They react with α, β -unsaturated esters and alkylidene malonates in the presence of t-BuOK and produce alkyl Cyclopropanecarboxylates.
