• General Description: Iodosilane (also known as silyl iodide) is a halogenated silane compound that can be conveniently synthesized via a PdCl₂- or NiCl₂-catalyzed hydrogen-halogen exchange reaction between hydrosilanes and alkyl iodides. This method offers a practical and economical route to produce iodosilanes, which serve as valuable reagents in organosilicon chemistry. While PdCl₂ demonstrates higher catalytic efficiency, NiCl₂ also facilitates the reaction, albeit with reduced activity. A notable limitation is the tendency of the reaction to yield fully halogenated products, making selective partial halogenation difficult.

PdCl₂ and NiCl₂-catalyzed hydrogen-halogen exchange for the convenient preparation of bromo- and iodosilanes and germanes

10.1016/S0022-328X(02)02147-2

The research investigates a method for synthesizing bromo- and iodosilanes, as well as germanes, using a hydrogen–halogen exchange reaction catalyzed by PdCl2 or NiCl2. The purpose of the study is to develop a versatile and convenient synthetic route for these compounds, which are important reagents in the creation of various organosilicon and germanium compounds. The researchers found that treating hydrosilanes with alkyl or allyl bromides in the presence of a catalytic amount of PdCl2 or NiCl2 resulted in the formation of bromosilanes in good to high yields. Similarly, using alkyl iodides led to the formation of iodosilanes. The reactions were more efficient with PdCl2, but NiCl2 was also effective, albeit with lower activity. The study concludes that this method provides a practical and economic way to synthesize a variety of bromo- and iodosilanes and germanes, which could be useful in the synthesis of complex organosilicon and germanium compounds. However, the selective halogenation of partially halogenated products remains a challenge, as the reactions tend to produce fully halogenated compounds even at early stages.
