  Enhancement of the Lewis acidity by substitution of sulfur-containing hetero aromatics in triarylboranes

  摘要：

  Triarylboranes hearing two thiophene, dimethylthiophene, or benzothiophene Units were synthesized. X-ray crystallographic analysis revealed the planar structure around the boron atom and non-bonding S-S interaction of the thiophene. They exhibited several intense absorption bands in the UV region. They were stable in the air for months and showed extremely strong Lewis acidities. (C) 2009 Elsevier Ltd. All Fights reserved.
