2-Mercapto-4-methyl-5-thiazoleacetic acid may be used as a capping agent in the preparation of fused spherical gold nanoparticles. It may also be used in the synthesis of eight-tin macrocyclic complex (a 40-membered macrocycle containing two distannoxane ladders). | [General Description]
2-Mercapto-4-methyl-5-thiazoleacetic acid is a thiazole derivative. It participates in the preparation of dinuclear [Au-(O4NCS2)]2 and tetranuclear [Au(SSCOOH)]4 complexes. | [Synthesis]
To the reactor were added 100 kg of acetylpropionic acid and 1000 L of carbon tetrachloride. Under stirring conditions, 176 kg of sodium bromide was added, followed by a slow dropwise addition of 260 kg of hydrogen peroxide solution. The reaction mixture was heated to 60 °C and maintained at this temperature for 2.5 hours. Upon completion of the reaction, water was added for washing to separate the organic and aqueous phases. The aqueous phase was treated as waste water. To the organic phase, 75 kg of ammonium dithiocarbamate, 1000 kg of water and 22 kg of sodium carbonate were added directly to the organic phase to carry out the cyclization reaction. After completion of the reaction, the aqueous phase was acidified with acid at pH=1.5 to precipitate the product. Finally, 132 kg of 2-mercapto-4-methyl-5-thiazoleacetic acid was obtained with 99.92% purity and 80.99% yield. | [References]
