三唑-膦-铜配合物(TAP-Cu)已被合成并用作可调谐和有效的催化剂,用于选择性合成氟代2-芳基-1 H-苯并[d]咪唑和1-苄基-2-芳基1小时一步法制得的简单醇中的苯并[d]咪唑衍生物。TAP-Cu对脱氢和借用氢反应均显示出优异且可调节的催化活性,首次证明了80多个例子。观察到配体在催化剂活性中起关键作用。机理研究和氘标记实验表明,反应是通过初始且可逆的醇脱氢进行的,从而生成氢化铜中间体。固态红外光谱法直接观察氢化铜诊断信号也支持了这一点。TAP-Cu-H络合物在912 cm -1处显示吸收可以分配给氢化铜拉伸。此外,也成功地进行了中间双亚胺的直接捕集。

activity. Mechanistic studies and deuterium labeling experiments indicated that the reactions proceeded by an initial and reversible alcohol dehydrogenation resulting in a copper hydride intermediate. This was also supported by the direct observation of a diagnostic copper hydride signal by solid‐state infrared spectroscopy. The TAP−Cu‐H complex showed absorptions at 912 cm−1 that could be assigned
