The following were synthesized for the first time by the catalytic method from the corresponding alkene and acid chloride; 1) 6-oxo-7-decenoic acid; 2) 8-methyl-6-oxo-7-nonenoic acid; 3) 4-oxodecanoic acid; 4) 6-oxododecanoic acid; 5) 7,7,8-trimethyl-6-oxo-8-nonenoic acid; 6) 7,7,8-trimethyl-6-oxononanoic acid; 7) 6-oxotridecanoic acid (this acid was prepared previously by organomagnesium synthesis [4]).
