A novel donor/acceptor carbene intermediate has been developed using diaryldiazoketones as carbene precursors. In the presence of the chiral dirhodium catalyst, Rh2(S-TPPTTL)4, diaryldiazoketones undergo highly regio-, stereo-, and diastereoselective C–Hfunctionalization of activated and unactivated secondary and tertiary C–H bonds. Computational studies revealed that the arylketo group behaves differently
