Functional Al/Cd Heterometallics─From Controlled Al(I) Transfer to Nucleophilic Transfer of Cadmium Ions.

ABSTRACT: Low-valent cadmium compounds have remained largely unexplored as electron reservoirs, with no precedent for their use in reduction or bond activation chemistry. Here, we address this gap by integrating low-valent aluminum into the cadmium coordination sphere. Aluminylene insertion into Cd{N(TMS)₂}₂ affords bi- and trimetallic cadmium aluminyls 1 and 2, featuring covalent yet tunable Al-Cd bonding. While 1 is irreversibly formed, 2 exhibits dynamic reactivity, enabling reversible [AlCp*]⁰ transfer─a rare and previously undocumented feature in heterobimetallic aluminum chemistry. Acting as a thermodynamically stable yet chemically reactive surrogate for free Al(I), 2 enables selective Al(I) shuttling to B, Cd, Zn, and Ag sub
