文摘

Stereoselective cyclopalladation of [(N-methyl-N-aryl)amino]methylferrocenes 1a–f (aryl = 4-CH₃OC₆H₄(a), 4-CH₃C₆H₄(b), C₆H₅(c), 4-ClC₆H₄(d), 3-ClC₆H₄(e), 3-O₂NC₆H₄(f)) with sodium palladium tetrachloride and followed by treatment with triphenylphosphine resulted in the cyclopalladated complexes 3a–f (aryl = same as before) in the form of raceme. The structure of 3a was determined by X-ray single crystal diffraction. Complex 3a crystallizes in triclinic, space group P-1 with a = 10.6685(14), b = 10.7412(14), c = 16.795(2) , α = 71.879(2), β = 85.798(2), γ = 64.523(2)°. The possible mechanism for the formation of 3 was discussed.
