SYNTHESIS, CHARACTERIZATION, AND BIOLOGICAL ACTIVITY OF SOME ORGANOTIN PYRAZOLECARBOXYLATES

Abstract

A series of organotin pyrazolecarboxylates of the general formula R _n SnL_{4 − n} have been synthesized and characterized by elemental analyses, IR, ¹H NMR, and mass spectroscopy. Biological activity determinations for selected compounds indicate that these compounds have antibacterial activity.

Keywords:

• Organotin
• Pyrazolecarboxylate
• Antibacterial activity

ACKNOWLEDGMENT

We are thankful to Professor Bingwu Li of the National Laboratory of Elemento-Organic Chemistry in Nankai University, for testing the antibacterial activity.
