Provided are a method for producing a sanshool, which can produce a sanshool in a short process and with high stereoselectivity, as well as a novel diene iron complex compound that is a stable intermediate useful for the production method. The diene iron complex compound is represented by the following general formula (I):
(in which A represents CO, P(RA)3, CN, NO, SO(RA)3, or N(RA)2; RA represents a straight chain or branched chain alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 12 carbon atoms; and one of R1 and R2 represents a hydrogen atom and the other one thereof represents a structure represented by the following formula (II)):
(in which R represents a hydrogen atom, a hydroxyl group, or a methyl group
