PdCl2 and NiCl2-catalyzed hydrogen–halogen exchange for the convenient preparation of bromo- and Iodosilane (cas 13598-42-0)s and germanes

Add time:08/27/2019    Source:sciencedirect.com

Bromination and iodination of hydrosilanes and germanes were studied. Treatment of hydrosilanes with an excess of ethyl, propyl, or allyl bromide in the presence of a catalytic amount of PdCl2 or NiCl2 gave bromosilanes in good to high yield by hydrogen–halogen exchange. By using methyl, propyl, or allyl iodide as the iodine source, similar iodination of hydrosilanes was readily performed. Halogenation of hydrogermanes also proceeded by similar treatment.
