by the reaction with dialkylmethylsilanes in the presence of new iron(II) piano-stool catalysts of general formula Cp∗Fe(CO)2Ar (Cp∗ = η5-C5Me5; Ar = Ph, 4-C6H4OCH3, 4-C6H4CH3, Fc). This transformation is promoted by UV light and affords a simple route for the preparation of unsymmetrical alkyl ethers.
醛的还原性醚化可以通过对反应与dialkylmethylsilanes在新的铁的存在下进行(II)通式Cp的钢琴凳催化剂*的Fe(CO)2的Ar(CP * =η 5 -C 5我5 ;氩= Ph,4-C 6 H 4 OCH 3,4 -C 6 H 4 CH 3,Fc)。紫外光促进了这种转变,并提供了制备不对称烷基醚的简单途径。
