The unique reactivity of silylated propargyltungsten and ‐molybdenum species with electrophiles provides a route to synthetically useful compounds. In the reaction with aldehydes, 1,4‐dioxy‐1,3‐dienes or, when conducted in the presence of Et 3 Al, silylated furans were generated in good yield. In reactions with enones or CO 2 , allenyl silane derivatives and silylated butenolides were obtained in good yield.
