The cross mono-coupling reactions of Grignard reagents with a,w-dibromoalkanes catalyzed by some copper salt complexes were studied. The use of N,N,N',N'-tetramethylethylenediamine could improve the reaction conditions and expand the scope of this method, and a series of long chain bromoalkanes (C18-30) were prepared
