Titanium-multicarbene complexes, namely organotitanium species having a plurality of titanium-carbene complex substructures, were easily prepared by the reaction of aromatic nuclei possessing spatially separated thioacetal moieties with the titanocene(II) reagent Cp2Ti[P(OEt)3]2. Reaction of these multicarbene complexes with aromatic ketones gave various highly conjugated compounds in good yields.
