Group VA salts and process for preparing same

Abstract

There are provided novel salts defined by the following Formula I: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 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; a hydrocarbyl group, such as defined above, carrying halogen, hydroxyl, alkoxy or aryloxy; and a sulfonato group (--SO.sub.3.sup.-) or an alkyl, aryl, alkenyl, cycloalkyl, aralkyl or alkaryl group carrying a sulfonato group; provided that at least one of R.sub.1, R.sub.2 and R.sub.3 is a sulfonato group or an alkyl, aryl, alkenyl, cycloalkyl, aralkyl or alkaryl, as defined above, carrying a sulfonato group; M is sulfur or oxygen, preferably oxygen; F is phosphorus, arsenic or antimony, preferably phosphorus; and X is a halogen radical selected from the group consisting of fluorine, chlorine, bromine and iodine, preferably 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: ##STR2## with an alpha-substituted ketone or aldehyde or an alpha-substituted thioketone or thioaldehyde defined by the following formula: ##STR3## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, F, M and X are as defined above.
