我们公开了一种1,4,7-三氮杂环壬烷(TACN)配体,其特征在于附加的硼刘易斯酸。与Cu(I)的金属化得到一系列四面体配合物,包括硼封端的氢化亚铜。我们证明了不同的反应模式作为化学氧化的函数:氢化物转移到CO2中的铜(I)状态和氧化剂诱导的H2演变以及炔还原。
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 CO2 in the copper(I) state and oxidant-induced H2 evolution as well as alkyne reduction.
