with ethyl acetate as the solvent. A simple iron- and silylchloridecatalyzed method for the preparation of symmetrical and nonsymmetrical ethers is presented. Various aldehydes and ketones were reductively etherified by using triethylsilane as a reducing agent in the presence of 2 mol% of iron(III) oxo acetate and 8 mol% of chloro(trimethyl)silane. The reactions can be carried out at ambient temperatures
Aldehydes and ketones undergo a smooth reductive etherification by polymethylhydrosiloxane (PMHS) in the presence of a catalytic amount of molecular iodine under mild conditions to afford the corresponding symmetrical ethers in excellent yields. This new reagent system (PMHS/I2) provides a simple and convenient route for the preparation of symmetrical ethers from carbonyl compounds.
醛和酮在温和的条件下,在催化量的分子碘的存在下,通过聚甲基氢硅氧烷(PMHS)进行平滑的还原醚化反应,从而以优异的收率得到相应的对称醚。这种新的试剂系统(PMHS / I 2)为从羰基化合物制备对称醚提供了一种简便的途径。
