A convenient procedure is developed for the preparation of selenolactones from unsaturated acids and diselenides using a catalytic amount of ammonium iodide in combination with m-chloroperoxybenzoic acid as the oxidant. This catalytic ring-closing method proceeds efficiently at room temperature under neutral conditions, and in short reaction times, to afford the corresponding selenolactones in good yields. Using the same reaction conditions, cyclic selenoethers and tellurocyclization products are prepared, thus extending the catalytic application of inorganic iodides in organic synthesis.

Integrated electrochemical reactors in automated flow systems were utilised for selenenylation reactions. The automation allowed multiple electrochemical reactions of a programmed sequence to be performed in a fully autonomous way. Many functionalised selenenylated products were synthesised in short reaction times in good to high yields.
