WebBoron is excreted mainly in the urine, and small amounts are excreted in the feces, sweat, breath, and bile [9,10]. Boron status is not routinely measured in clinical practice. Most studies suggest that urinary boron levels correlate with boron intakes [2,4,16,17]. WebAryl boron compounds, Arn B (OH) 3 − n ( n = 1–3), bearing electron-withdrawing aromatic groups such as triarylboranes, diarylborinic acids, and arylboronic acids, represent a new class of air stable and water-tolerant Lewis acid or Brønsted acid catalyst in organic synthesis. In particular, tris (pentafluorophenyl)borane, primarily used ... joe crash
