Abstract

Cu(I)-Hydrido complexes supported by dibenzo[b,f]azepinyl P-alkene hybrid ligands and stabilized by electrostatic interactions in a Cu–H⋯KCl⋯BR₃ arrangement can be trapped with CO₂ at low temperature to afford Cu(I)-formates. The complexes are isolable with and without a pendant BEt₃ group and show strong Cu–O and weak B–O interactions.
