lignin-derived substrates have emerged as desirable biorenewable chemical feedstocks for coupling reactions. A radical-mediated conversion of phenol derivatives to anilines is reported, using unfunctionalized hydroxamic acids as the N-centered radical source. The applicability of this triethyl phosphite mediated O-atom transfer approach, which tolerates a range of steric and electronic demands to naturally
酚类,木质素衍生的底物已成为偶联反应的理想生物可再生化学原料。据报道,使用未官能化的异羟肟酸作为N中心自由基源,可将苯酚衍生物自由基介导地转化为苯胺。在这项工作中证明了该亚磷酸三乙酯介导的O原子转移方法的适用性,该方法可耐受对天然存在的酚和木质素模型的一系列空间和电子需求,从而可获取相应的苯胺衍生物。
