the transformation of these terminalalkynes into allenes and further to internalalkynes under mild conditions. To the best of our knowledge, this example is the first of an organomagnesium‐catalyzed isomerization of alkynes. Notably, the reactions proceeded through temporally separated autotandem catalysis, thus allowing the isolation of the allene or internalalkyne species in good yields. Mechanistic
