    摘要: A process is provided for preparing nickel ylides wich are themselves novel compounds defined by the following Formula I:
    wherein R,, R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 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 carbon 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; a hydrocarbyl group, such as defined above, carrying halogen, hydroxyl or alkoxy or aryloxy; and a sulfonato group (-SO 3 - ) or an alkyl, aryl, alkenyl, cycloalkyl, aralkyl or alkaryl group carrying a sulfonato group; provided that at least one sulfonato group is located in R 4 , R s and R. and at least one of R 4 , R s and R 6 is aryl; 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 ligand defined by the following formula:
    and then reacting the resulting sulfonated ligand with (1) a zero valent nickel compound and (2) a ylide defined by the following formula: wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , E, F and M are as defined above, provided that at least one of R 4 , R 5 and R 6 is an aryl group.
