Transition state structures of the Cs2CO3-induced C-H activation through a concerted metalation–deprotonation process to result in II and II(a). A With 5,6-diCOOiPr NBE (barrier height 20.5 kcal/mol), where a coordination between Cs and carbonyl O was observed, and B With the unsubstituted NBE (barrier height 22.6 kcal/mol). Different orientations of TFP were noted.
