Aluminylenes (R-Al) are aluminium analogs of carbenes. In contrast to isolable carbenes, aluminylenes are extremely rare species. In the past years, pioneered by Schnöckel, Roesky and Power, a few free aluminylenes and their complexes have been reported. Such compounds have the aluminium atom in the oxidation state +I, which contrasts with classical organoaluminium derivatives that contain the element in the +III oxidation state. Aluminylenes, either in their free state or in the coordination sphere of a Lewis base, are capable of coordinating to transition metals and activating inert chemical bonds. Free aluminylenes are emerging as potent synthetic platforms for unusual aluminium species.
铝烯（R-Al）是卡宾的铝类似物。与可分离的卡宾不同，铝烯是极为罕见的物种。在过去的几年中，由 Schnöckel、Roesky 和 Power 等人开创，已经报道了一些游离的铝烯及其配合物。这些化合物中的铝原子处于+I 氧化态，与通常含有+III 氧化态的元素的经典有机铝衍生物形成对比。游离的铝烯，无论是在其自由状态还是在路易斯碱的配位球中，都能够与过渡金属配位并激活惰性化学键。游离的铝烯正成为不常见的铝物种的有效合成平台。
