The titled iron complexes derived from 3-iodo-1-trimethylsiloxypropenes and reacted with carbon nucleophiles such as NaCH(CO2Et)2 to give the corresponding nucleophile addition products in high yields.The addition occurred at the 3-position of the ligands with high regioselectivity.However, the iron complexes derived from 2-alkyl-3-iodo-1-trimethylsiloxypropenes underwent cyclization reaction with the same siloxypropenes to give dihydropyran derivatives.The diversity in the modes of reactions of the iron complexes are discussed.
