Abstract

The reagent Na2Fe (CO) 4 prepared in situ in THF by the reduction of Fe (CO) 5 with sodium naphthalenide reacts with certain alkenes in the presence of CuCl to bring about isomerization of the alkenes. Thus the 1-alkenes (1-dodecene, 1-decene, safrole and allyl benzene) are isomerized to trans-2-alkenes, and β-pinene is isomerized to α-pinene. Reactions involving BrCH2CH2Br in place of CuCl give similar results.
