The coordination chemistry of bidentate fluorinated alkoxy-imino ligands onto Al(III) centers has been studied. The proligands (CF3)2C(OH)CH2C(R1)═N–R2 (ONR1,R2}H; R1 = Me, Ph; R2 = Ph, CH2Ph, cyclohexyl; 1a–d) react selectively with AlMe3 (0.5 or 1.0 equiv) and AlMe2(OiPr) or Al(OiPr)3 (0.5 equiv) to give the corresponding monoligand compounds ONR1,R2}AlMe2 (2a–d) and the bis-ligand compounds ONR1
