一般描述
Ethyl 4-methyl-4-pentenoate is an olefin ester. It undergoes iron carbonyl-promoted isomerization to α,β-unsaturated esters. Reaction of ethyl 4-methyl-4-pentenoate with CH3OBOCH3+ was examined in a small Fourier-transform ion cyclotron resonance mass spectrometer equipped with a permanent magnet.

Ultraviolet photolysis of stoichiometric amounts of methyl oleate and Fe(CO)(5) in hexanes solvent at 0 degrees C gives Fe(CO)(3)(eta(4)-alpha,beta-ester) in which the alpha,beta-unsaturated ester isomer of methyl oleate is stabilized by eta(4)-oxadiene pi coordination of the olefin and ester carbonyl
