Zusammenfassung

The product of an Mg/CCl4-induced reductive coupling of guaiazulene reacts with TiCl3·3THF to yield, after oxidation with HCl/O2, R,S-8,8′-biguaiazulenide titanium dichloride, which contains a CC bond between its two guaiazulenide ligand moieties. A similar reaction sequence starting from 3-phenyl-1,2-dihydropentalene gives unbridged R,S-bis(4-exo-phenyl-4H-5,6-dihydropentalenide)titanium dichloride.
