formation of fluorescent polymorphs and SC-SC transition exhibited tunable and switchablesolidstate fluorescence. The non-planar TPE core has been made use to demonstrate high contrast stimuli induced reversible fluorescence switching. Overall, the present studies attempted to gain information on the structural design for developing SC-SC transforming functional organic fluorescent materials that
A palladium/norbornene catalyzed two-component coupling process involving acylation/cyanation of aryl iodides is reported. In this work, aryl acyl nitrile compounds are cleverly selected to provide both nitrile and acyl sources by palladium-catalyzed cleavage of the C–CN bond as both an electrophilic reagent and a termination reagent. This is the first example of C–CN bond cleavage bifunctionalization
报道了钯/降冰片烯催化的双组分偶联过程,涉及芳基碘化物的酰化/氰化。在这项工作中,巧妙地选择了芳基酰基腈化合物,通过钯催化的 C-CN 键断裂来提供腈和酰基源,作为亲电试剂和终止试剂。这是芳基碘化物 C-CN 键断裂双功能化的第一个例子。经过一系列重要的NBE衍生物的筛选,顺利得到了芳基碘化物双官能化产物。该策略具有广泛的底物范围和良好的官能团兼容性。此外,该合成方案在合成各种O 、 N 、 C取代的异吲哚啉酮方面表现出良好的应用。
