A structurally characterized cationic aluminium complex [(AT)Al(DMAP)][OTf] (3) stabilized through a relatively nonbulky aminotroponate (AT) ligand is reported (DMAP = 4-(dimethylamino)pyridine). This compound was found to work as an excellent mononuclear main-group catalyst of the cyanosilylation of a variety of aldehydes and ketones. Loadings of 1 to 2 mol% of this catalyst consumed these substrates in just 5 to 30 min at room temperature.
据报道，一种结构特征明确的阳离子铝配合物[(AT)Al(DMAP)][OTf] (3)通过相对较小的氨基环庚三烯酚酮(AT)配体得以稳定（DMAP = 4-(二甲基氨基)吡啶）。发现该化合物可作为多种醛和酮氰基硅烷化反应的优良单核主族催化剂。该催化剂负载量为1至2 mol%时，在室温下仅需5至30分钟就能消耗这些底物。
