Ir-Catalyzed -COOH directed site-selective B-H/C-H dehydrogenative cross-coupling of o-carborane with thiophenes has been achieved for the first time. Without any pre-functionalization, carboranyl carboxylic acids and thiophenes can serve as suitable coupling partners, resulting in the preparation of 4-thienyl-o-carboranes in a simple one-pot process for potential applications in materials.
首次实现了铱催化的邻碳硼烷的-COOH导向的位点选择性B-H/C-H脱氢交叉偶联与噻吩的反应。无需任何预官能团化，碳硼烷基羧酸和噻吩可作为合适的偶联伙伴，通过简单的一锅法制备4-噻吩基邻碳硼烷，用于材料的潜在应用。
