heterogeneous Cu catalysts and systematically evaluated their composition and catalytic activity in azide-alkyne cycloadditions as a model reaction. The use of sustainable graphite nanoplatelets (GNPs) afforded a stable CuI catalyst with good recyclability properties, which are compatible with flow conditions, and able to catalyze other reactions such as the regio- and stereoselective sulfonylation of alkynes (addition
石墨烯衍生物作为载体的使用改善了非均相催化剂的性能,其中最常用的是氧化石墨烯(GO)。为了探索更绿色的可能性,并深入了解不同石墨烯载体(GO,rGO,炭黑和石墨纳米片)的作用,我们在相同的标准条件下制备了多种异质铜催化剂,并进行了系统评估它们在叠氮化物-炔烃环加成反应中的组成和催化活性作为模型反应。使用可持续的石墨纳米片(GNP)可提供具有良好可回收性的稳定CuI催化剂,该催化剂可与流动条件兼容,
