- Nucleophilic aromatic substitutions: Hydrodealkoxylation, hydrodehalogenation, and hydrodeamination of alkoxy, halogeno, and amino (η6-arene)tricarbonylchromium complexes
-
Hydrodealkoxylation, -dehalogenation, and -deamination, occur while lithium triethylborohydride is added to [η6-alkoxy-, halogeno-, and -(dimethylamino)benzene]tricarbonylchromium complexes. In the case of (η6-benzene)tricarbonylchromium, addition of deuteride to the benzene ring gives reversibly an anionic tricarbonyl(η5-cyclohexadienyl)chromium complex which can be trapped by triphenyltin chloride to yield the neutral binuclear complex (η5-C6H6D)(CO)3Cr-Sn(C 6H5)3. The latter complex molecular structure has been confirmed by single-crystal X-ray diffraction analysis. Empirical formula C27H21DCrO3Sn: triclinic system, space group P1, z = 2, a = 8.961(4) A?, b = 10.853(5) A?, c = 12.713(2) A?, α = 85.15(3)°, β = 86.26(2)°, γ = 72.40(4)°, R = 0.033, Rw = 0.037 (unit weight).
