Synthesis and theoretical studies of gallium complexes back-shielded by a cage-shaped framework of tris(m-oxybenzyl)arene.

ABSTRACT

Cage-shaped gallium complexes with a back-shielding framework of tris(m-oxybenzyl)arene were synthesized, their bottom arene rings tuned their characteristic Lewis acidity, which was supported by theoretical calculation as well as catalytic application in a hetero Diels-Alder reaction.
