通过三甲基铝对末端炔烃的直接Lewis碱催化铝化反应,开发了一种高效、温和的混合二甲基炔基铝试剂。使用双(三甲基硅基)甲胺可以在室温下实现金属化,只需1%的催化剂负载量。
An efficient and mild access to mixed dimethylalkynylaluminum reagents has been developed via a direct Lewis base-catalyzed alumination of terminal alkynes by trimethylaluminum. The use of bis(trimethylsilyl)methylamine enables the metalation at room temperature with only 1% of catalyst loading.
