Facile 1,2‐ and 1,3‐group migrations : The first donor‐free silyl(silylene)–iron complex 1 has been prepared and structurally characterized (see scheme). This complex reacts with t BuNC under mild heating to give a disilanyl complex 2 through 1,3‐alkyl and aryl migration and 1,2‐silyl migration processes. Complex 2 is an example of how organosilicon species bound to transition‐metal centers can change their form in a dynamic fashion (Mes=2,4,6‐trimethylphenyl).
