The reactions were run under N. To 92 g. (BuO)3B in Et2O was added with Dry Ice cooling an ethereal solution of ferrocenyl-Li prepared from 17.6 g. ferrocene by treatment with BuLli (from 39 g. BuCl and 7.6 g. Li). The mixture was allowed to come to room temperature; on the following day it was treated with aqueous H2SO4 and the organic layer extracted with aqueous KOH. The alk. extracts on acidification gave first 2.9 g. 1,1′-ferrocenylenediboronic acid (I) (total yield 13%), decomposing at 180°, then ferrocenylboronic acid (II), 26% yield, m. 1438°. The latter refluxed with aqueous ZnCl2 gave ferrocene; the diboronic acid is hydrolyzed similarly. Treatment of II with hot aqueous acetone solution of HgCl2 gave 76% yellow ferrocenylmercuric chloride, decompose 192-4° (from xylene). Similarly aqueous CuCl2 gave 84% chloroferrocene, m. 59-60° (from EtOH). CuBr2 gave 80% bromoferrocene, m. 32-3°. I and aqueous CuCl2 gave 1,1′-dichloroferrocene, m. 75-7° (from EtOH); CuBr2 gave 76% 1,1′-dibromoferrocene, m. 50-1° (from EtOH). Treatment of II with ammoniacal solution of Ag2O gave metallic Ag, and extraction with Et2O gave 52% diferrocenyl, decomposing 230°, along with 31% ferrocene. Diferrocenyl is sparingly soluble in petr. ether, soluble in MePh, C6H6, dioxane, and tetrahydrofuran.
