ortho ‐C−H bond alkenylation proceeded at N ‐arylimido ligands bridging two titanium metal centers, in which the Ti 2 N 2 four‐membered core was flexibly twisted to form the appropriate conformation for both ortho ‐C−H bond activation and insertion reactions of the internal alkyne to give six‐membered titanacycles. Kinetic studies, deuterium‐labeling experiments, and computational studies revealed the reaction mechanism. More information can be found in the Full Paper by H. Tsurugi, K. Mashima et al. on page 586 ff.
