ABSTRACT

ABSTRACT

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.
