The ability of titanium–phosphine complexes to induce C—C coupling reactions with alkenes, alkynes, and carbonyl compounds has been applied to the synthesis of metallacycles.[307] The reaction of [Ti(Cp)2(PMe3)2] (116) with a range of alkynes affords the corresponding titanacyclopentadienes 176-178 and 132 and titanium–alkyne complex 179 (Scheme 89).[308,309] Homocoupling of allenes with low-valent titanium complexes [Ti(Cp)2(PMe3)2] (116) or [Ti(Cp)2(PMe3)(H2C=CH2)] (180) affords bis(alkylidene)titanacyclopentane 182 via titanium–allene complex 181 (Scheme 89).[310]
