Abstract
Amides of β-mercaptohydrocinnamic acid were prepared by the addition of hydrogen sulfide to amides of cinnamic acid. Amides of thiosalicylic acid were also prepared. Some of these mercapto-amides formed stable chelates with copper and nickel. Cobalt chelate was not stable enough to be separated in pure state. The ratio of the ligand to the metal was 1:1 in copper chelate and 2:1 in nickel chelate. It was found that these chelate compounds were S-O chelating compounds from the infrared spectra.
