nanoclusters stabilized by a hydrophilic polymer, poly(N-vinyl-2-pyrrolidone) (Au:PVP), catalyzed the intramolecular hydroamination of toluenesulfonamides to unactivated alkenes/alkynes in EtOH under aerobic and basic conditions. The reaction proceeds via anti-addition of toluenesulfonamide to the alkenes assisted by π-activation of the gold clusters.
金纳米团簇通过亲水性聚合物聚(N-乙烯基-2-吡咯烷酮)(Au:PVP)稳定,在有氧和碱性条件下,在EtOH中将甲苯磺酰胺的分子内加氢胺化为未活化的烯烃/炔烃。该反应通过在金簇的π-活化的辅助下将甲苯磺酰胺抗加成到烯烃上而进行。
