Unexpected Meerwein–Ponndorf–Verley (MPV) reduction products have been obtained during attempts to prepare aluminum and indium isopropoxide complexes of an imino-phenolate ligand derived from 8-aminoquinoline (ONNqui}−). Reaction of the imino-phenol proligand ONNqui}H and Al(OiPr)3 in toluene/THF at 90 °C affords selectively [ONNqui}ONHNqui}Al] (1a), which contains a monoanionicONNqui}− ligand
