Abstract

In contrast to previous assertions, we find that B2Br4 reacts readily with ethylene to generate BBr2CH2CH2BBr2, which can be isolated in 95% yield. While it has been reported numerous times that the disproportionation of B2C14, which eventually yields BC13 and the polyhedral boron halides B, X,(n= 8-12), is slowed by the addition of haloalkenes, we have found that the disproportionation rate of both B2Cl4 and B2Br4 is also significantly ...
