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.
