A novel LiOPiv-promoted and palladium-catalysed formal [2 + 2 + 2] annulation reaction of vinyl triflates and o-silylaryl triflates via aryne intermediates has been developed. This methodology affords good to excellent yields of 9,10-substituted phenanthrenes (including cyclohexa[l]phenanthrenes) and is tolerant of a variety of functional groups such as ester, cyano, and ketone.

通过LiOPiv促进的和钯催化的芳烃与乙烯基三氟甲磺酸酯合成9,10-菲†

已经开发了一种新的LiOPiv促进和钯催化的经由芳烃中间体的乙烯基三氟甲磺酸酯和邻甲硅烷基芳基三氟甲磺酸酯的正式[2 + 2 + 2]环化反应。这种方法得到很好的9,10-菲取代（包括环己[优异的产率升]菲）和是多种官能团，例如酯基，氰基，和酮的耐受性。
