Abstract
We herein report hydrazine-directed, Rh(III) catalyzed (4+2) annulation of -alkyl aryl hydrazines with sulfoxonium ylides as a safe carbene precursor. The reaction shows excellent functional group tolerance with broad substrate scope, scalability and site selectivity. Finally, photophysical studies indicated that some of these compounds have interesting fluorescence properties.
摘要
我们在此报告了一种由肼导向、Rh(III)催化的（4+2）环化反应，反应中使用了-sulfoxonium 叶立德作为安全的卡宾前体，与 -烷基芳基腙反应。该反应具有出色的官能团耐受性、广泛的底物范围、可扩展性和位点选择性。最后，光物理研究表明，这些化合物中的一些具有有趣的荧光性质。
