  Facial Selectivity in the Diels−Alder Reactions of 5-Chloro-, 5-Bromo-, and 5-Iodo-1,3-cyclopentadiene and Derivatives

  摘要：

  A variety of dienophiles was used to assess the facial selectivity of Diels-Alder reactions in a series of 1,3-cyclopentadiene derivatives (1-3, 6-10) in which chlorine, bromine, and iodine were plane-nonsymmetric atoms pitted against hydrogen or methyl at C-5. The results were rationalized in terms of the major factor controlling the facial selectivity being related to steric hindrance between the diene and the dienophile. Selectivity did not correlate with reactivity. Facial selectivity in the reactions with 4-phenyl-1,2,4-triazoline-3,5-dione as the dienophile was also influenced by a second significant factor, postulated to be filled-orbital repulsion with the halogen substituent.

  Oxidation of Yb metal by iodopentamethylcyclopentadiene (IC5Me5) afforded Li[Yb(C5Me5)I3] and Li[Yb(C5Me5)2I2] sequentially in the presence of LiI; analogous anionic chloride complexes, the new divalent complex Yb(C5Me5)2, and methyl derivatives of both di- and tri-valent systems were obtained via metathetical reactions.

  The present disclosure relates to a novel metallocene compound. The metallocene compound according to the present disclosure may be used for the preparation of an olefin-based polymer, may have excellent ability, and may produce an olefin-based polymer having a relatively high molecular weight compared with the case of using a catalyst composition having a similar structure due to the structural and electrical steric hindrance effect.
