## Abstract Details of cobalt‐catalyzed cross‐coupling reactions of alkyl halides with allylic Grignard reagents are disclosed. A combination of cobalt(II) chloride and 1,2‐bis(diphenylphosphino)ethane (DPPE) or 1,3‐bis(diphenylphosphino)propane (DPPP) is suitable as a precatalyst and allows second
## Abstract In the reactions of Grignard reagents and __n__‐butyllithium the presence of transition metals and complexing solvents facilitates the formation of anion radicals. High radical concentrations, observable for some days at laboratory temperature, and very well resolved e.s.r. spectra of t
