Abstract
Transmetallation, or transfer of a group between metals or metalloids, is arguably the most understudied elementary organometallic step, especially with early transition metal complexes. In this work, the reactivity of the organoborane, HB(pin), with yttrium complexes bearing a tris(amido) redox-active ligand was investigated. B–O bond cleavage was observed instead of the expected B–H bond cleavage that would result from transmetallation. Additionally, the tris(amido) ligand was transferred from yttrium to boron. New boron complexes (2) and (3) were synthesized and characterized and an intermediate Y–B complex (4) featuring the B–O bond cleavage is also reported. This work demonstrates the incompatibility of HB(pin) as a transmetallating reagent for yttrium complexes bearing a tris(amido) ligand.
期刊介绍：
Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
