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.
