Transfer of amide and 2-methoxyethoxy groups and sodium encapsulation in the reaction of TaCl₃[N(TMS)₂]₂ with sodium Bis(2-methoxyethoxy)aluminum Hydride: X-ray Structure of [NaAl{N(TMS) ₂}(OCH₂CH₂OMe)₃]₂

Abstract

The reaction between the tantalum compound TaCl₃[N(TMS) ₂]₂ and the hydridic reducing agent sodium bis(2-methoxyethoxy)aluminum hydride (Vitride) has been investigated in toluene solution at room temperature and found to afford the dimeric aluminate complex [NaAl{N(TMS)₂}(OCH₂CH₂OMe)₃] ₂ as the sole isolable product. The molecular structure of the product establishes the existence of a four-coordinate aluminum atom and the formal transfer of the 2-methoxyethoxy and bis(trimethylsilyl)amide groups to the aluminate product. The aggregation of two NaAl{N(TMS)₂}(OCH ₂CH₂OMe)₃ units serves to bind the two sodium cations in a crown-ether fashion through six ancillary oxygen atoms.
