Applicazioni

A Pseudomonas species which utilized 3-chlorobenzoic acid as a carbon source converted this compound to 3-hydroxybenzoic and 2, 5-dihydroxybenzoic acids. A methanogenic consortium able to use 3-chlorobenzoic acid as its sole energy and carbon source was enriched from anaerobic sewage sludge. A Pseudomonas putida strain 87 capable of assimilating 3-chlorobenzoic acid as a sole source of carbon and energy (3Cba+) was isolated. coupling of 3-chlorobenzoic acid with phenylboronic acid proceeds at room temperature using 0.5 % Pd and at 100°C using 0.1 % Pd to provide the coupled product in 97 % yeild.

Note

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.

The unprotected acid undergoes lithiation at the 2-position with 2.2 moles of s-BuLi in the presence of TMEDA; subsequent reaction with dibromotetrachloroethane provides access to 2-bromo-3-chlorobenzoic acid: Tetrahedron Lett., 36, 881 (1995); Bull. Soc. Chim. Fr., 133, 133 (1996).
