Abstract
A vicinal ethylene bridged S/B frustrated Lewis pair (FLP) in situ generated by a hydroboration reaction of phenyl vinyl sulfide, reacts with p-tert-butylphenylacetylene by ethene/alkyne exchange and subsequent 1,2-addition of a second alkyne equivalent to give a zwitterionic sulfonium/borate product.
摘要
由苯乙烯基硫醚的硼氢化反应原位生成的邻位乙烯桥联 S/B 受阻路易斯对（FLP），通过乙烯/炔烃交换和随后第二个炔烃当量的 1,2-加成与对叔丁基苯乙炔反应，得到两性离子锍/硼酸产物。
