A process is provided for preparing nickel ylides which are themselves novel compounds defined by the following Formula I: <CHEM> 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 carbon 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 iodine, 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 selected from the group consisting of a hydrocarbyl group as defined above, a sulfonato group (-SO3<->) or a sulfonated hydrocarbyli group; M is sulfur or oxygen, preferably oxygen; E is phosphorus, arsenic, antimony or nitrogen, preferably phosphorus; and F is phosphorus, arsenic or antimony, preferably phosphorus. The process comprises sulfonating a metal ylide defined by the following Formula II: <CHEM> to obtain the sulfonated ylide defined by the following Formula III: <CHEM> 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: <CHEM> , |
