The McMurry reaction involving low-valent titanium species accomplishes coupling of two carbonyl groups to furnish aUcenes. The low-valent titanium species is generated either from TiCls/LAH , TiCls/Mg or TiCU/Zn-Cu. When one or both carbonyl substrates carry one or more additional double bonds, dienes or polyenes result from this reaction (equation 109) . The McMurry coupling reaction is remarkably selective and a wide variety of functionalities are tolerated. This reaction can be carried out in both inter- and intramolecular modes to furnish a variety of dienes and polyenes. Synthesis of dienes and polyenes where McMurry coupling has been a key reaction is given in Table 21 . [Pg.428]
