Capitalizing on cobalt: A new route to silyl enol ethers employing a Co-catalyzed cascade reaction featuring a tandem hydrosilation/hydrogen-transfer reaction is reported. The low catalyst loading, mild reaction conditions, and unique η2-silane resting state showcase the impressive utility of this seldom used transition-metal catalyst in C[BOND]H activation reactions (see scheme; VTMS = vinyltrimethylsilane; Cp* = 1,2,3,4,5-pentamethylcyclopentadiene).
