approach. Quantitative 13C NMR proves to be an efficient tool for the characterization of oligoglycols. The corresponding telluride of oligoglycol 17 is synthesized and used as a good catalyst for Wittig-type reactions in preparing both disubstituted and trisubstituted οlefins in good to high yields.
几种具有游离羟基的季戊四醇衍生的低聚乙二醇1可以通过收敛方法容易地制备。定量13 C NMR被证明是表征低聚乙二醇的有效工具。合成了相应的低聚乙二醇17的碲化物,并将其用作Wittig型反应的良好催化剂,以高收率或高收率制备二取代和三取代的烯烃。
