A new and efficient method for the synthesis of bromosilanes from hydrosilanes using Br3CCOOEt/PdCl2 as the catalyst

Bromosilanes were prepared conveniently and efficiently via the reaction of hydrosilanes and Br3CCOOEt in the presence of a catalytic amount of PdCl2 in refluxing THF over 15 min in high yields. The developed methodology was further applied for the one-pot synthesis of silyl ethers and silyl esters in excellent yields.

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

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.

The Mechanism of the Reaction of Molecular Bromine with Organosilicon Hydrides

The kinetics of the bromination of 7 triarylsilanes and 14 other organosilicon hydrides by molecular bromine in CCl4 have been determined by the stopped flow method.For triethylsilane, Arrhenius parameters have been measured in octane and CCl4, and solvent effects determined in other solvents of different polarity.The results accord with a molecular mechanism involving one molecule of bromine and one of the organosilicon hydride, with partial positive charge build-up on silicon in the transition state.
