Article abstract of DOI:10.1021/om00017a043

(2,4-pentadienal)Fe(CO)₃ complexes containing electron donor 5-substituents (OMe, OCOR, NR₂) have been prepared and resolved via oxazolidine or imine derivatives or through incorporation of a homochiral dialkylamino auxiliary. Absolute configurations have been established by X-ray crystallography. Crystal data: (10) orthorhombic, space group P2₁2₁2₁, a = 6.607(2) ?, b = 10.459(2) ?, c = 15.411(3) ?, Z = 4, R₁ = 0.0920 for 138 parameters and 1787 observed reflections: (11) monoclinic, space group P2₁/a, a = 7.1237(7) ?, b = 20.257(2) ?, c = 8.1669(8) ?, β = 96.73(1)°, Z = 4, R₁ = 0.0367 for 184 parameters and 3211 observed reflections; (14a) orthorhombic, space group P2₁2₁2₁, a = 8.6105(8) ?, b 9.5644(8) ?, c = 29.271(3) ?, Z = 4, R₁ = 0.0423 for 300 parameters and 4497 observed reflections; (15b) orthorhombic, space group P2₁2₁2₁, a = 6.7400(9) ?, b = 12.526(3) ?, c = 24.254(4) ?, Z = 4, R₁ = 0.0454 for 246 parameters and 3387 observed reflections.
