A transition-metal-free method for the synthesis of indolines has been developed. In the presence of K2CO3, the cyclization reaction of N-(ortho-chloromethyl)arylamides and iodonium ylides proceeded smoothly at room temperature in moderate to good yields.
已经开发了用于合成二氢吲哚的无过渡金属的方法。在K 2 CO 3的存在下,N-(邻-氯甲基)芳基酰胺和碘鎓碘化物的环化反应在室温下以中等至良好的收率顺利进行。

A newroute for the synthesis of 2(5H)-furanones is presented via Pd(PPh3)4-catalyzed cascade reaction of acetlenic acids with iodonium ylides using K2CO3 as the base. The cascade proceeds through dehydrogenation coupling and cyclization under mild conditions.
The effects of different copper (and some other) catalysts on the conversion of triphenyl- and tetraphenyl- diazocyclopentadienes and of some phenyliodonium αα′-dicarbonylylides into arsonium and other ylides

Diazo-compounds or iodonium ylides may be converted into arsonium and other ylides when heated in solution with triphenylarsine or other suitable carbene (or carbenoid) acceptor, and with a suitable Cu derivative present. The effects of using different copper complexes and salts are described and discussed. Other metal derivatives were for the most part ineffective as catalysts.

A mild and general cycloaddition of arynes with iodonium ylides protocol has been developed for the synthesis of benzofurans. In the presence of CsF, ortho-silyl aryltriflates were reacted with iodonium ylides smoothly at room temperature in moderate to good yields.
