formation of aryl vinyl sulfide cation radicals from the corresponding neutral precursors via reaction with tris(4-bromophenyl)aminium hexachloroantimonate in the context of a cation radical Diels−Alder addition to 1,3-cyclopentadiene does not occur via outer sphere electron transfer but by a mechanism involving strong covalent interaction between the aminium salt acting as an electrophile and the aryl vinyl
有证据表明,在阳离子自由基 Diels-Alder 加成到 1,3-环戊二烯的背景下,通过与三(4-溴苯基)胺六氯锑酸盐反应,从相应的中性前体形成芳基乙烯基硫醚阳离子自由基不会通过外层发生。球体电子转移,但通过一种涉及作为亲电子试剂的胺盐和作为亲核试剂的芳基乙烯基硫化物底物之间强共价相互作用的机制。
