金(I)催化的碳-碳键形成反应继续吸引着合成界,但与许多传统的金属催化剂相比,研究较少。[1]在许多情况下,阳离子金(I)-物质活化不饱和CC键并使其异构化或官能化以通过包括金-π-络合物、金-乙烯基化合物和金-卡宾的反应性中间体来构建分子复杂性。支持这些中间体主要是基于金(I)的有机金属化学,虽然计算研究和分离的建议催化中间体已被报道。[2-5]我们报告了一个看似简单的金(I)催化反应的机理研究,并证明了双核有机金属中间体的重要性。虽然在DFT研究中已经假设了类似的双核物种,[5 b]双金中间体还没有被原位检测到,并且它们的反应性还没有被表征。
Gold (I)-catalyzed carbon-carbon bond forming reactions continue to fascinate the synthetic community but are less well investigated than many conventional metal catalysts.[1] In many cases a cationic gold (I)-species activates an unsaturated CC bond and isomerizes or functionalizes it to build molecular complexity through reactive intermediates that include gold-π-complexes, gold-vinyls, and gold-carbenes. Support for these intermediates is mainly based on gold (I) organometallic chemistry, though computational studies and the isolation of proposed catalytic intermediates have been reported.[2–5]We report mechanistic studies on a seemingly simple gold (I)-catalyzed reaction and demonstrate the importance of dinuclear organometallic intermediates. While similar dinuclear species have been postulated in DFT studies,[5b] di-gold intermediates have yet to be detected in situ and their reactivity characterized.
