NOVEL GROUP VA SALTS AND PROCESS FOR PREPARING SAME Abstract Of The Disclosure There are provided novel salts defined by the following Formula I: Image wherein R1, R2, R3, R4 and R5 are either alike or dif- ferent members selected from the group consisting of hy- drogen, 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 car- bon 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, alkoxy or aryloxy, and a sulfonato group (-SO3-) or an alkyl, aryl, alkenyl, cycloalkyl, aralkyl or alkaryl group carrying a sulfonato group; provided that at least one of R1, R2 and is a sulfonato group or an alkyl I aryl, alkenyl, cyclo- alkyl, aralkyl or alkaryl, as defined above, carrying a sulfonato group; M is sulfur or oxygen, preferably oxygen; F is phosphorus, arsenic or antimony, preferably phosphor- us; and X is a halogen radical selected from the group consisting of fluorine, chlorine, bromine and iodine, pre- ferably chlorine and bromine, a tosyl group (a toluene sulfonato group), or an acetate group. The process for preparing these salts comprises reacting a ligand defined by the following formula: Image with an alpha-substituted ketone or aldehyde or an alpha- substituted thioketone or thioaldehyde defined by the following formula: Image wherein R1, R2, R3, R4, R5, F, M and X are as defined above.
