A highly efficient heterogeneous ruthenium(III)-catalyzed reaction of diaryl diselenides with alkyl halides was achieved in DMF at 100?°C in the presence of 2?mol% of an MCM-41-immobilized bidentate nitrogen ruthenium(III) complex [MCM-41-2N-RuCl3] and zinc, yielding a variety of unsymmetrical diorganyl selenides in good to excellent yields. This new heterogeneous ruthenium catalyst can easily be prepared via a simple two-step procedure from commercially readily available and inexpensive reagents, and recovered by filtration of the reaction solution and recycled for at least eight times without a significant loss of activity.

The bimetallic reagent Sn(II)/Cu(II) in [bmim]BF4 was efficiently used for the cleavage of diaryl diselenides and disulfides and reacts with a variety of organic substrates, such as organic halides, acid chlorides, and β-amino mesylates affording the diorganyl selenides and sulfides within very short reaction times, under mild conditions and with excellent yields, using BMIM-BF4 as a reusable solvent.

A convenient and efficient method was developed for the synthesis of alkyl phenyl selenides, sulfides, and selenoesters in one-pot reaction by using indium metal. The reaction showed the selectivity for tert-alkyl, benzylic, and allylic halides over primary and secondary alkyl halides. For the reaction of primary and secondary alkyl iodides and bromides, the yields of selenides were improved by the addition of a catalytic amount of iodine.
