Abstract: cf. CA 55, 18692e; 56, 7355a. The aldol condensation of 1,1'-diacetylferrocene with aliohatic aldehydes and consequent cyclization with intramol. Michael addn. was described. This reaction is similar to that of the basic catalyzed condensation of BzH and its derivs. with 1,1'-diacetylferrocene and 1-acetyl-1'-acylferrocene out the yield is very much lower, from 9 to 18%. With HCHO, 1,1'-(α,α'-dioxopentamethylene)ferrocene, yellow crystals, m. 253°, was formed; with AcH, 1,1'-(α,α'-dioxo-γ-methylpentamethylene)ferrocene, yellow needle crystals, m. 251.5-53°; with propionaldehyde, 1,1'-(α,α'-dioxo-γ-ethylpentamethylene)ferrocene, yellow crystals, m. 214.5-16.5°; with butyraldehyde, 1,1'-[α,α'-dioxo-γ-propylpentamethylene]ferrocene, yellow crystals, m. 239-40°; with isobutyraldehyde, 1,1'-(α,α'-dioxo-γ-isopropylpentamethylene)ferrocene, yellow crystals, m. 269.5°, and with isovaleraldehyde, 1,1'-(α,α'-dioxo-γ-isobutylpentamethylene)ferrocene.
