The diiodoalanes (C5H7R2N2)AlI2 [6; R = Me (a), Ph (c)] are obtained from the corresponding alanes (C5H7R2N2)AlH2 (5) and [Me3NH]I in good yields. (C5H7R2N2)AlI2 [6; R = iso-Pr (b)] is alternatively prepared, as well as 6a, from the corresponding vinamidine lithium compound C5H7R2NLi (8) and AlI3. (C5H7Me2N2)AlBr2 (9a) is formed according to both methods. The X-ray structures of 6a and 6b are reported
