to their reactivity as electrophilic alkynylation reagents, they undergo regioselective additions to the C−C triple bond. The products thus obtained can be used for the synthesis of Z-vinyl sulfones and 9,10-substituted phenanthrenes.
进一步评估了 5-(炔基)苯并噻吩鎓盐的合成潜力。除了作为亲电炔基化试剂的反应性外,它们还对 C−C 三键进行区域选择性加成。所得产物可用于Z-乙烯基砜和9,10-取代菲的合成。
