Abstract

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.
