A half-sandwich 1,2-azaborolyl (Ab) ruthenium complex, (Ab–CCPh)RuCl(PPh3)2 (1), has been synthesized by treating RuCl2(PPh3)3 with lithium 1,2-azaborolide L-1, or by treating either RuCl2(PPh3)3 or RuHCl(PPh3)3 directly with 1,2-azaborole LH-1. It is evaluated as a suitable precatalyst in [2 + 2] cycloadditions of norbornene derivatives with DMAD and in atom transfer radical additions of halogenated compounds with olefins.
通过将 RuCl2(PPh3)3 与 1,2-氮杂硼酸锂 L-1 一起处理,或将 RuCl2(PPh3)3 或 RuHCl(PPh3)3 直接与 1,2-氮杂硼酸 LH-1 一起处理,合成了一种半夹心 1,2-氮杂硼酸(Ab)钌配合物 (Ab-CCPh)RuCl(PPh3)2 (1)。在降冰片烯衍生物与 DMAD 的[2 + 2]环加成反应中,以及卤代化合物与烯烃的原子转移自由基加成反应中,它被评估为一种合适的前催化剂。
