Silver-Catalyzed Formal Inverse Electron-Demand Diels–Alder Reaction of 1,2-Diazines and Siloxy Alkynes

A highly effective silver-catalyzed formal inverse electron-demand Diels–Alder reaction of 1,2-diazines and siloxy alkynes has been developed. The reactions provide ready access to a wide range of siloxy naphthalenes and anthracenes, which are formed in good to high yields, under mild reaction conditions, using low catalyst loadings
