Abstract

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 tBuNC 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).
