The use of anhydrous CeCl3 as a catalyst for the synthesis of 3-sulfenyl indoles
摘要:
Anhydrous CeCl3 was successfully used as a catalyst for the synthesis of several 3-sulfenyl indoles in good to excellent yields through the reaction of indole with N-(alkylthio) and N-(arylthio)phthalimides in DMF. (C) 2010 Elsevier Ltd. All rights reserved.

coupling of heteroarenes with thiophenols and phenothiazines has been developed under mild and environmentally benign reaction conditions. For the first time, NOx+ was applied for catalytic C–S and C–N bond formation. A comprehensive scope for the C–H/S–H and C–H/N–H cross-dehydrogenative coupling was demonstrated with >60 examples. The sustainable cross-coupling conditions utilize ambient oxygen as the
杂芳烃与硫酚和吩噻嗪的催化交叉脱氢偶联已在温和且环境友好的反应条件下得到发展。首次将NO x +用于催化C–S和C–N键的形成。用60多个例子证明了C–H / S–H和C–H / N–H交叉脱氢偶联的综合范围。可持续的交叉偶联条件利用环境氧作为末端氧化剂,而水是唯一的副产物。

A convenient method was developed for the preparation of thiolated compounds via a DBU-catalyzed aerobic cross-dehydrogenative coupling (CDC) reaction. The established protocol is environmentally friendly and operationally simple. Substrates like (hetero)aryl acetates, (hetero)aryl ketones, and indoles could be transformed into the corresponding thiolated products in moderate to high yields and further
