Conjugateadditions and conjugate addition-alkylations proceed with very high stereoselectivity to α,β-unsaturated acyls of n5 -CpFe(CO)(PPh3). Oxidative cleavage of the products provides high yields of organic acid derivatives (esters, β-lactams) with almost complete control of relative stereochemistry.
