Abstract:

The reaction of LAlH(2) (L = HC(CMeNAr)(2), Ar = 2,6-iPr(2)C(6)H(3)) (1) with 3-methylphenylboronic acid and 3-fluorophenylboronic acid resulted in the boroxine-linked aluminum compounds LAl[OB(3-CH(3)C(6)H(4))](2)(μ-O) (2) and LAl[OB(3-FC(6)H(4))](2)(μ-O) (3), respectively. LAl[OB(2-PhC(6)H(4))(OH)](2) (4) was synthesized by the reaction of 1 with 2-biphenylboronic acid. Compound 4 is the intermediate analogue to those, which we postulated for the formation of 2 and 3. The reaction of 1 with 3-hydroxyphenylboronic acid resulted in the first metal benzoboroxole oxide LAl[OB(o-CH(2)O)C(6)H(4)](2) (5), which is formed from a compound with B-(OH)(2) and C-OH functionalities.
