An atom‐economical synthesis of 3‐alkylidene‐3H‐indole N‐oxides has been developed via a tandem reaction of propargylic alcohols and nitrosobenzenes in the presence of boron trifluoride etherate (BF3⋅Et2O) as catalyst. This method offers great potential for the synthesis of biologically important 3‐alkylidene‐3H‐indole N‐oxides and related derivatives.
