Arylspiroborates Derived from 4‐<i>tert</i>‐Butylcatechol and 3,5‐Di‐<i>tert</i>‐butylcatechol and Their Antimicrobial Activities

Abstract

A family of arylspiroborates has been prepared by the addition of either 4‐ tert ‐butylcatechol or 3,5‐di‐ tert ‐butylcatechol to boric acid and an alkali metal hydroxide. All compounds were characterized fully using multinuclear NMR spectroscopy and by elemental analyses. A single crystal X‐ray diffraction was carried out on potassium (bis‐(3,5‐di‐tertbutyl[1,2‐benzenediolato(2‐)‐ O , O ′]borate)) ( 8 ). All compounds displayed appreciable anti‐microbial activities.
