Ferrocene reacts with an excess of boron triiodide or boron tribromide in hexane solution to give mixtures of 1,3,1′-tris- and 1,3,1′,3′-tetrakis- (dihalogenoboryl)ferrocene. The borylation proceeds stepwise, the intermediates being essentially the known dihalogenoborylferrocene and 1,1′-bis- (dihalogenoboryl)ferrocene compounds, although small am ounts of 1,3-bis(dihalogenoboryl)- ferrocene can also be identified. 1H, 11B and 13C NMR data are given.
