The [Cp*CpZrNCMe 3 (thf)] system provides the first direct measurement of kinetic selectivity in sp, sp 2 , and sp 3 CH bond activation with Group 4 imido complexes. This feature allows the design of selectivity and mechanistic experiments to probe the 1,2‐RH‐addition event. Substrates reacting with the highest relative rates generally form the most thermodynamically stable products. Cp*=η 5 ‐C 5 Me 5 , Cp=η 5 ‐C 5 H 5 .
