In an example, the silica-supported catalyst was prepd. by adsorption of a soln. of 0.7 mg of PtCl4 in 1.0 g of 1-ethyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imidate on 5 g of granulated silica (0.2-0.5 mm particles) followed by reaction of 6.3 g of allyl chloride with 11.7 g of trichlorosilane at 100 Deg, giving (trichloropropyl)trichlorosilane with 70% yield and 73% selectivity. In another example, the catalytic soln. of PtCl4 in 1-ethyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imidate was reused three times with any loss of catalytic activity. on SciFinder (R)
