资源简介：
The acetylenic thioether PhSCCSPh undergoes a
rapid 1,1-carboboration
reaction with facile −SPh migration upon treatment with B(C6F5)3 to yield the borylated ketene dithioacetal
product (PhS)2CC(C6F5)B(C6F5)2 (8a). The X-ray crystal
structure analysis revealed an intramolecular sulfur–boron
contact. The thioether PhCCSPh undergoes an analogous 1,1-carboboration
reaction with B(C6F5)3. The resulting
vicinal S/B frustrated Lewis pair undergoes 1,2-addition reactions
to terminal acetylenes to give the respective zwitterionic six-membered
heterocyclic sulfonium/borate products (all three examples were characterized
by X-ray diffraction).
