A new and unstable Bi(III) species was prepared using a trianionic m-xylene-based N−C−N pincer ligand. Depending on the nature of the substituents on the nitrogen, this species either spontaneously forms Bi(III) dimers, or undergoes H2 loss from the benzyl positions, forming a Bi(I) species.
使用基于三阴离子间二甲苯的 N-C-N 钳形配体制备了一种新的且不稳定的 Bi(III) 物质。根据氮上取代基的性质,该物质要么自发形成 Bi(III) 二聚体,要么从苄基位置发生 H 2损失,形成 Bi(I) 物质。
