Reaction of the small closo carboranes 1,6-C2B4H6 and 2,4-C2B5H7 with BX3 (X = halogen, phenyl): A method of preparing 3 -Substituted 2,4-C2B5H7 derivatives and preparation of 2-Br2B-closo-1,6-C2B4H5

The reaction of closo-2,4-C2B5H7 with BX3 (X = Cl, Br, I, C6H5) at elevated temperatures (270°C for BCl3, 160°C for BBr3, 120°C for BI3, 160°C for B(C6H5)3) results in halogen, or phenyl, substitution primarily at the 3-position of the carborane (i.e. 3-X-closo-2,4-C2B5H6). closo-2,4-C2B5H7 also reacts with (CH3)3CCl at 270°C to give 3-Cl-closo-2,4-C2B5H6. A closo carborane containing a trigonal boron σ-bonded to a cage carborane, 2-Br2B-closo-1,6-C2B4H5, is prepared from closo-1,6-C2B4H6 and BBr3 at 265°C.
