A new direct allylation of aromatic compounds has been developed. A mixture of allylsilane, allylgermane, or allylstannane and thallium (III) trifluoroacetate was allowed to react with an aromatic compound, a nucleophile, to give allylation product (s) in good yields via an allylcationic species. Thus, the usefulness of these allylmetal compounds as allyl cation equivalents was established.
一种新的芳香化合物直接烯丙基化方法已经被开发出来。让烯丙基
硅烷、烯丙基
锗烷或烯丙基
锡烷与
三氟乙酸铊(III)的混合物和芳香化合物(一种亲核试剂)反应,通过烯丙基阳离子生成烯丙基化产物,且产率良好。由此,这些烯丙基
金属化合物作为烯丙基阳离子等价物的实用性得到了确定。
