Abstract Of The Disclosure A process is provided for preparing nickel ylides which are themselves novel compounds defined by the following Formula I: Image wherein R1, R2, R3, and R7 are either alike or different members selected from the group consisting of hydrogen, alkyl radicals having from about one to about 24 carbon atoms, preferably from about one to about 10 carbon atoms; aryl radicals having from about six to about 20 carbon atoms, preferably from about six to about 10 carbon atoms; alkenyl radicals having from about two to about 30 carbons atoms, preferably from about two to about 20 carbon atoms; cycloalkyl radicals having from about three to about 40 carbon atoms, preferably from about three to about 30 car- bon atoms; aralkyl and alkaryl radicals having from about six to about 40 carbon atoms, preferably from about six to about 30 carbon atoms; a halogen radical selected from the group consisting of fluorine, chlorine, bromine and io- dine, preferably chlorine; a hydroxyl group; an alkoxy or aryloxy group and a hydrocarbyl group, such as defined above, carrying halogen, hydroxyl or alkoxy or aryloxy; R4, R5 and R6 are either alike or different members se- lected from the group consisting of a hydrocarbyl group as defined above, a sulfonato group (-SO3-) or a sulfonated hydrocarbyl group; M is sulfur or oxygen, preferably oxy- gen; E is phosphorus, arsenic, antimony or nitrogen, pre- ferably phosphorus; and F is phosphorus, arsenic or anti- mony, preferably phosphorus. The process comprises sul- fonating a metal ylide defined by the following Formula II: Image to obtain the sulfonated ylide defined by the following Formula III: Image wherein R1, R2, R3, R7, F and M are as defined above. The sulfonated ylide is reacted with a base to obtain the metal ylide defined by the following Formula IV: Image wherein R1, R2, R3, R7, F and M are as defined above and A is the cationic portion of the base used. This ylide is then reacted with (1) a zero valent nickel compound and (2) a ligand having the formula: Image wherein R4, R5, R6 and E are as defined above.
