Abstract

Gold(III) chloride is a highly efficient catalyst for the cyanosilylation of various ketones and aldehydes. The reactions were complete within 30 minutes at room temperature in the presence of only 1 mol% gold(III) chloride, yielding the corresponding cyanohydrin trimethylsilyl ethers in very good yields.
