Herein, we describe the intermolecular amination of allyl alcohols with sulfamates, which have been underutilized as nitrogen nucleophiles for allylic amination. Methyl sulfamate is a good nucleophile in the presence of mercuric triflate and efficiently generates monoallylation products in excellent yield at room temperature. Furthermore, the solid-supported mercuric catalyst silaphenyl mercuric triflate
在此,我们描述了烯丙醇与氨基磺酸盐的分子间胺化,氨基磺酸盐作为氮亲核试剂未充分利用以进行烯丙胺化。在三氟甲磺酸汞存在下,氨基磺酸甲酯是一种良好的亲核试剂,并在室温下以优异的产率有效地生成单烯丙基化产物。此外,固体负载的汞催化剂三氟甲磺酸硅苯基汞也显示出显着的烯丙基胺化催化活性。
