Description	A dealkylsilylation reaction between alumazene [2,6-(i-Pr)2C6H3NAlMe]3 (1) and tris(trimethylsilyl) ester of phosphoric acid (2) in a 1:3 molar ratio provides the heteroadamantane molecule (MeAl)[2,6-(i-Pr)2C6H3N]3{Al[OP(OSiMe3)3]}2(O3POSiMe3) (3). Compound 3 was characterized by analytical and spectroscopic methods and its molecular structure was established by a single-crystal X-ray diffraction experiment. Moreover, trialkyl and triaryl phosphates, and dialkyl phosphonates react with 1 at elevated temperature to afford an intractable mixture of products. The reaction of phosphonic acids with 1 proceeds under decomposition to yield 2,6-diisopropylaniline and aluminophosphonates.
