synthesis of various oxindoles from carbamoyl chlorides. Under the optimum reaction conditions, with Ad2PBu as a ligand, tBuCONHOH as an additive, and a CO atmosphere, selective C(sp3)H activation proceeded in the presence of a C(sp2)H bond. Ad=adamantyl.
颇为选择:一个新的战略是为各种羟吲哚从氨基甲酰氯综合方法。在最佳反应条件下,以Ad 2 PBu为配体,t BuCONHOH为添加剂,并在CO气氛下,在C(sp 2)H键的存在下进行选择性C(sp 3)H活化。Ad =金刚烷基。
