- Some aspects of the chemistry of 1,2′-(B5H8)2, 2,2′-(B5H8)2, and their derivatives
-
Various derivatives of 1,2′-(B5H8)2 and 2,2′-(B5H8)2 were produced via halogenation and deprotonation reactions. The rearrangement of the parent compounds and some of their derivatives was studied in the presence of Lewis bases. Cleavage of the intercage σ bond in 1,2′-(B5H8)2 was observed in the presence of halogens and hydrogen halides, while boron-boron σ-bond cleavage was not observed in 2,2′-(B5H8)2.

- Synthesis and characterization of 1-(Cl2B)B5H8 and 1-(Cl2B)-2-ClB5H7: A new boron-boron σ bond
-
Two new 1-(dichloroboryl)pentaborane(9) derivatives, 1-(Cl2B)B5H8 and 1-(Cl2B)-2-ClB5H7, have been produced via the reaction of BCl3 with B5H9 and 2-ClB5H8, respectively, in the presence of Friedel-Crafts catalysts. These compounds are the first examples of σ bonding between borane cluster atoms and external trigonal boron atoms. The boron-boron bonds undergo cleavage at elevated temperature in the presence of diethyl ether and insert ethylene at ambient temperature to form 1-[2-(dichloroboryl)ethyl]pentaborane(9) derivatives.
