Abstract

The reaction of LAlH₂ (L = HC(CMeNAr)₂, Ar = 2,6-ⁱPr₂C₆H₃) (1) with cyclopentylboronic acid resulted in the boroxine-linked aluminum compound LAl[OB(C₅H₉)]₂(μ-O) (2). However, the reaction of 1 with 3- hydroxymethylphenylboronic acid gave an eight-membered boroxine-linked dialuminum compound of composition [LAlOB(3-OHCH ₂C₆H₄)]₂ (3) with a spiro center at each of the aluminum atoms. The two complexes were characterized by 1H NMR, IR spectroscopy, elemental analysis, and single crystal X-ray structural analysis.
