Regio- and stereo-selective coupling reactions of cyclo-1,3-dienes catalysed by titanium aryloxide compounds

Highly selective non-Diels–Alder dimerization of cyclohexa-1,3-diene and cross-coupling of either cyclohexa-1,3-diene or cycloocta-1,3-diene with α-alkenes is catalysed by titanium aryloxide compounds.
