Bis(hexafluoroacetylacetonato)copper(II) is a very effective catalyst for the preparation of ylides from diazo compounds under mild conditions even down to room temperature.It appears that the lower the temperature at which the reaction can be conducted the purer the product which results.Its use in preparing arsonium, stibonium, bismuthonium, sulphonium, telluronium, and thiouronium ylides is described.
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 ineffetive as catalysts.
