A new route to E-Stilbenes, based on the transition metal free, KOtBu/DMF promoted activation and direct coupling of alcohols with phenyl acetonitriles, is reported. A variation allowing the selective synthesis of N-Heteroarenes and a mechanism proceeding via the activation of alcohols under alkyl formate intermediates are also reported.
报道了一种基于不含过渡金属、KO t Bu/DMF 的E-二苯乙烯的新途径,它促进了醇与苯基乙腈的活化和直接偶联。还报道了一种允许选择性合成 N-杂芳烃的变化以及通过在甲酸烷基酯中间体下活化醇进行的机制。
