Abstract

Reaction of an imidotitanium complex, stabilized by a tridentate diamidopyridine ligand, with the methyl acetylenes MeC2Me and MeC2Ph led to C–H-activation of the substrate and subsequent C–N coupling to give azatitana-tetracycles which may be viewed as dimetallated enamines; the same compounds were obtained in reactions with the allenes Me(H)C[double bond, length half m-dash]C[double bond, length half m-dash]CH2 and Ph(H)C[double bond, length half m-dash]C[double bond, length half m-dash]CH2.
