Cover Picture: Aluminum Dihydroxide with Terminal OH Groups: An Unprecedented Congener of Boronic Acid (Angew. Chem. Int. Ed. 10/2003)

42_10/2003This week's catch is an unprecedented aluminum compound of the form [LAl(OH)2], prepared via the hydrolysis of [LAlI2] in a two-phase toluene/liquid ammonia system. The solid-state structure reveals a weakly hydrogen-bonded dimer; electrostatic potential analysis indicates that electrophilic attack at the oxygen sites is preferred, and that π-electron density is increased upon formation of the dimer. More details of this congener of RB(OH)2 are given in the Communication by H. W. Roesky and co-workers on page 1132ff.
