General description

Benzhydroxamic acid (BHA) reacts with BiPh3 or Bi(O(t)Bu)3 to afford novel mono- and di-anionic hydroxamato complexes, having anti-bacterial activity against Helicobacter pylori. Three-dimensional structure of recombinant horseradish peroxidase-BHA complex has been studied.

Application

Benzhydroxamic acid may be employed for the Pd-catalyzed synthesis of benzisoxazolones.
