Acylation and Coupling Reactions

Acylation and Coupling Reactions. Reagents used for the preparation of unsymmetrical ketones by coupling alkyl halides with acid chlorides include activated nickel, prepared by the action of lithium and naphthalene on nickel(II) chloride in glyrae (Vol,8, 

0-Substitution of a,B-unsaturated ketones with vinyl iodides under 

The cobalt complex (24), on treatment with alkyl-lithium reagents, forms an acyl complex which will react with allylic halides 

Benzylic halides may be carbonylated to the corresponding esters by bubbling carbon monoxide through a solution of the halide in the 

5-diene)rhodium(I) chloride dimer or with the same catalyst in
