一个新的方向:芳基亚砜的亲核邻丙烯酰化反应利用了亲核剂分子间传递到硫,然后分子内继而传递到碳(见图)。这种简单的、不含金属的方法是通用的,对于丙烯基亲核试剂具有区域特异性,并且完全选择性地用于邻丙叉化而不是烯丙基化的产物。
A new direction: The nucleophilic ortho-propargylation of aryl sulfoxides exploits intermolecular delivery of the nucleophile to sulfur followed by an intramolecular relay to carbon (see scheme). The simple, metal-free procedure is general, regiospecific with regard to the propargyl nucleophile, and completely selective for products of ortho-propargylation over allenylation.© 2013 WILEY-VCH Verlag GmbH & Co.
