摘要

这项研究揭示了一种使用光致伸缩性膦配体实现 ON-ON 有机金属催化过程的策略。该方法利用了单金属和双金属金配合物的区域变异反应性（π- 与 σ,π- 激活炔基取代的脲底物所产生），通过分子内氢化作用，选择性地形成二氢喹唑啉酮或吲哚甲酰胺产物。

Divergent Reactivity of E/Z-Azobenzene-Based Phosphine-Gold Catalysts: Toward an ON-ON Catalytic Photoswitch Process

This work discloses a strategy for the implementation of ON-ON organometallic catalytic processes using photoresponsive phosphine ligands. The approach leverages on the regiodivergent reactivity of mono- and bimetallic gold complexes that result from π- vs σ,π-activations of alkynyl-substituted urea substrates, for the selective formation of either dihydroquinazolinone or indole-carboxamide products, via intramolecular hydroamidation.

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
