We disclose a 1,4,7-triazacyclononane (TACN) ligand featuring an appended boron Lewis acid. Metalation with Cu(I) affords a series of tetrahedral complexes including a boron-capped cuprous hydride. We demonstrate distinct reactivity modes as a function of chemical oxidation: hydride transfer to CO in the copper(I) state and oxidant-induced H evolution as well as alkyne reduction.
我们公开了一种 1,4,7-三氮杂环壬烷（TACN）配体，其特点是带有附加的硼路易斯酸。用 Cu(I) 进行金属化得到一系列四面体配合物，包括硼封端的一价铜氢化物。我们证明了作为化学氧化函数的不同反应模式：在铜（I）态下向 CO 转移氢化物和氧化剂诱导的 H 释放以及炔烃还原。
