Abstract
Process for preparing olefins and more specifically a compound of formula ** (See formula) ** which comprises treating a compound of formula ** (See formula) ** with a weak base, and then acidify; in which compound, R is a member of the group consisting of levialkyl, halolevialkyl, alkylcyclo, ** (See formula) ** wherein X1 is selected from the group consisting of hydrogen, halogen, levyalkyl, levialkoxyl, carboxyl and levyalkylsulfonyl, and ** (See formula) ** where X1 is as already defined; X is selected from the group consisting of hydrogen, halogen, trifluoromethyl, levyalkyl, nitro and levialkoxyl, and when there are two X radicals attached to adjacent carbon atoms of the benzene ring, they form when a 1,3-butadienylenic chain is combined; Z is selected from -SO-R2 and -SO2-R2, where R2 is selected from the group consisting of levyalkyl, 2-amino-2-carboxylealkyl, halolevialkyl, alkoxycarbonyl, levialkyl, carboxylealkyl, cycloalkyl, cycloalkylalkyl, ** (See formula) ** wherein X2 is selected from the group consisting of hydrogen, halogen, levyalkyl, trifluoromethyl, levialkoxy, carboxyl and levyalkylsulfonyl; ** (See formula) ** where X2 is as already defined ** (See formula) ** where R and X have the meanings of before; and -CnH2n-Z, where Z is as already said; m is in each case an integer of value 1-4, and n, also in each case, an integer of value 1-5.
