文摘

A dealkylsilylation reaction of alumazene [2,6-(i-Pr)₂C₆H₃NAlMe]₃(1) with trimethylsilyl methylsulfonate in a 1:2 molar ratio in tolueneafforded a supramolecular cyclic hexamer {Me[2,6-(i-Pr)₂C₆H₃NAl]₃(O₃SMe)₂}₆ (2) composed of six intact alumazene rings andpossessing two types of bridging sulfonate groups. Changing thereagent molar ratio to 1:3 caused the third sulfonate to partiallysubstitute the last alumazene methyl group in an ² fashion andintroduced a disorder in the crystal lattice.
