通过应用金/光氧化还原双催化体系，在室温下使用等摩尔量的重氮盐实现了炔醇或炔基氢过氧化物芳基偶联的方法。通过利用可见光介导的过程，避免了先前芳基化Meyer-Schuster重排方案所需的过量外部试剂（氧化剂或碱）和高温。
A method for the arylative coupling of alkynols or alkynyl hydroperoxides using equimolar amounts of diazonium salts at room temperature has been achieved through application of a gold/photoredox dual catalytic system. The excess of external reagents (oxidant or base) and high temperatures required by previous arylative Meyer-Schuster rearrangement protocols are avoided by exploitation of a visible light-mediated process.
