The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Bromoferrocene( cas:1273-73-0 ) is researched.Computed Properties of C10BrFe.Lee, Mei Tsu; Foxman, Bruce M.; Rosenblum, Myron published the article 《Cofacial metallocenes. Synthesis and crystal structure of 1,8-diferrocenylnaphthalene》 about this compound( cas:1273-73-0 ) in Organometallics. Keywords: crystal structure ferrocenylnaphthalene syn preparation; mol structure ferrocenylnaphthalene syn preparation; cyclic voltammetry ferroenylnaphthalene syn preparation; ferrocenylnaphthalene crystal structure oxidation preparation; diferrocenylnaphthylene crystal structure oxidation preparation; naphthalene diferrocenyl crystal structure oxidation. Let’s learn more about this compound (cas:1273-73-0).
The optimal synthesis of 1,8-differocenylnaphthalene (I) was the coupling of 1,8-diiodonaphthalene and ferrocenylzinc chloride in the presence of ferrocenylphosphine-containing catalyst PdLCl2, giving 58% of I with 94% selectivity. The x-ray crystal structure of I showed that the naphthalene ring and bonds from the peri-C atoms to the cyclopentadienyl rings were highly distorted. The 2 substituted cyclopentadienyl rings were rotated by ∼46° from the perpendicular to the naphthalene ring. Cyclic voltammetry of I showed 2 reversible, one-electron waves. The monocation I+BF4- derived by oxidation of I with AgBF4, had an intervalence transfer band at 1600 nm (εmax 200), not shown by the corresponding dication of I. I+ was best represented as a weakly interacting mixed-valence system.
