  Doubly intermolecular alkene diamination is achieved with electron-rich, terminal alkenes through the use of a hypervalent iodine (PhI(OAc)2) reagent, iodide, and electron-rich amines. Mono- and disubstituted amines combine with electron-rich alkenes, particularly o-hydroxystyrenes, to achieve the greatest level of generality. This operationally straightforward protocol, unreliant on conventional metal-based

  通过使用高价碘（PhI（OAc）2）试剂，碘化物和富含电子的胺，可以用富含电子的末端烯烃实现双分子间烯烃的金属化。单取代和二取代的胺与富电子的烯烃，特别是邻羟基苯乙烯结合使用，以实现最大程度的通用性。该操作简单易行的协议，不依赖于常规的基于金属的激活，可与各种官能团兼容。

  Phenols were vinylated at the ortho-position with ethyne in the presence of SnCl(4)-Bu(3)N reagent. The reaction was applicable to phenols possessing either electron-donating or electron-withdrawing groups. 2,6-Divinylphenols were synthesized under modified conditions. A reaction mechanism involving carbostannylation of alkynyltin and phenoxytin was discussed.
