In the presence of small amounts of p-thiocresol, hydrostannylation of propargyl p-tolyl sulfide promotes the unexpected formation of (Z)-1,2-bis(organostannyl)olefin instead of yielding normal addition products. The application of a non-refocusing INEPT pulse sequence in 119Sn NMR spectroscopy allows the determination of its stereochemistry by comparison of observed patterns with calculated spectra
在少量对硫甲酚的存在下,炔丙基对甲苯基硫醚的加氢苯乙烯基化反应会促进(Z)-1,2-双(有机甾烷醇)烯烃的意外形成,而不是产生正常的加成产物。通过在119 Sn NMR光谱中应用非重聚焦INEPT脉冲序列,可以通过比较观察到的谱图和计算得出的光谱来确定其立体化学。
