Siloxymethylation of oxygen-containing compounds by a new catalytic reaction, HSiR3/COCo2(CO)8, is described with emphasis laid on stereoselectivity. In the catalytic reaction, the carbon-oxygen bond in the substrates is cleaved and displaced by a trialkylsiloxymethyl group. The siloxymethylation takes place with inversion, racemization, or retention at the reaction sites, depending on the structure
描述了通过新的催化反应HSiR 3 / COCo 2(CO)8进行的含氧化合物的甲硅烷氧基甲基化,重点是立体选择性。在催化反应中,底物中的碳-氧键被三烷基甲硅烷氧基甲基基团裂解和置换。取决于底物的结构,甲硅烷氧基甲基化以转化,外消旋或保留在反应位点的方式发生。
