a) Experimental LFER analysis and computational study29 of the bromination using NBS. b) Comparison of transition‐state energies for aryl germanes and aryl silanes. Free energies in (a) and (b) computed at the CPCM (DMF) M06/6–311++G(d,p) (SDD)//ωB97XD/def2SVP level of theory. To account for charged intermediates, geometry optimizations were performed with an implicit solvent model. Free energies are given in kcal mol−1.
