Monocyclopentadienyl titanium complexes supported by functionalized carboxylate ligands

► New monocyclopentadienyl titanium complexes with functionalized carboxylate ligands have been synthesized. ► Tris-carboxylate- and alkyl-carboxylate titanium species were isolated from protonolysis processes with carboxylic acids. ► Insertion of tBuNC in an alkyl-titanium bond gave the corresponding iminoacyl-containing complex.
