The amide-directed cobalt(III)-catalyzed C–H amidation of ferrocene carboxamides using 1,4,2-dioxazol-5-ones as robust and efficient amidating reagents has been developed. This reaction proceeds efficiently under mild reaction conditions with good functional group tolerance, providing expedient access to a broad range of ferrocenes containing a nitrogen group on the Cp ring.
已经开发了使用1,4,2-二恶唑-5-酮作为稳固而有效的酰胺化试剂的酰胺导向的钴(III)催化的二茂铁羧酰胺的CH酰胺化反应。该反应在温和的反应条件下以良好的官能团耐受性有效进行,可方便地接近Cp环上含氮基的二茂铁。
