Insertion reactions of α,ω-bis-carbodiimides
(RNCN)2X (1–5: R = Et, t-Bu, Ph; X = C3H6, C4H8) with 2 equiv of AlMe3 yielded the dinuclear tethered
bis-amidinate–alane
complexes [RNC(Me)NAlMe2]2X (R = Et, X = C4H8 (6); R = t-Bu,
X = C3H6 (7), C4H8 (8)). Analogous reactions with 4 equiv of AlMe3 resulted in the coordination of two additional AlMe3 molecules, yielding the tetranuclear bis-amidinate complexes [EtN(AlMe3)C(Me)NAlMe2]2X (X = C3H6 (9), C4H8 (10)) and [t-BuNC(Me)N(AlMe3)AlMe2]2X (X = C3H6 (11),
C4H8 (12)). In addition, equimolar
reactions between (RNCN)2X (R = Et, X = C3H6, C4H8; R = Ph, X = C4H8) and 2 equiv of AlMe3 at elevated temperatures
occurred with intramolecular cyclization and formation of [EtNC(Me)NC3H6N(AlMe3)CNEt]AlMe2 (13) and [RNC(Me)NC4H8N(AlMe3)CNR]AlMe2 (R = Et (14), Ph (15)). Hydrolysis of 11 gave the protonated free ligand
PhNC(Me)NC4H8N(H)CNPh (16) in high
yield. 6–16 were characterized by
elemental analyses, multinuclear NMR (1H, 13C) and IR spectroscopy, and single-crystal X-ray diffraction (7, 10–14, 16).
