A novel, very simple and effective synthetic method for the formation of alkylaluminum complexes with terminal hydroxy group via hydrolysis of cyclopentadienylaluminum compounds has been found. Investigations of the hydrolysis of cyclopentadienylaluminum complexes (L)Al(Me)Cp (1) and (L)Al(Et)Cp (2) (L = HC[(CMe)(2,6-'Pr(2)C(6) H(3)N)](2)) have shown that the reaction leads to the formation of (L)AI(Me)OH (3) and (L)AI(Et)OH (4), respectively. The high selectivity of the hydrolysis was revealed. The crystal structures of 1, 2 and 4 were determined.
