## Abstract Details of cobaltβcatalyzed crossβcoupling reactions of alkyl halides with allylic Grignard reagents are disclosed. A combination of cobalt(II) chloride and 1,2βbis(diphenylphosphino)ethane (DPPE) or 1,3βbis(diphenylphosphino)propane (DPPP) is suitable as a precatalyst and allows second
