A direct, efficient, atom- and step-economic functionalization of allylic C−H bonds integrated with CO2 reduction to syngas, over SiO2-supported single Ni atom-decorated CdS quantum dots (QDs), is reported for the first time. Such a protocol not only bypasses additional oxidant/reductant and pre-functionalization to afford a broad range of allylic C−C products with moderate to excellent yields, but
首次报道了在 SiO 2支撑的单 Ni 原子修饰的 CdS 量子点 (QD) 上,烯丙基 C−H 键的直接、高效、原子和步骤经济的官能化与 CO 2还原成合成气的集成。这样的方案不仅绕过了额外的氧化剂/还原剂和预官能化,以提供范围广泛的具有中等至优异产率的烯丙基 C−C 产品,而且还有效地产生了可调节的合成气。
