substrates decorated with various substituents at different positions were all well accommodated. Preliminary mechanistic studies show that silver salt acted as a Lewis acid to facilitate both C-C cleavage of the cyclobutanone moiety and the subsequent metathesis between C═O and C≡C bonds.
首次实现了由AgSbF6催化的

环丁酮的开环/
炔烃羰基复分解序列,以在温和条件下提供多取代的
萘基酮。很好地容纳了在不同位置装饰有各种取代基的一系列基材。初步的机理研究表明,
银盐起
路易斯酸的作用,既促进了
环丁酮部分的CC裂解,又促进了C═O和C≡C键之间的易位。
