Transborylation of alkenylboranes with diboranes

Exchange of boryl moieties between alkenylboranes and diboron reagents has been postulated as a stereospecific cross-metathesis pathway with concomitant formation of mixed diboron reagents. DFT calculations propose a mechanism for the stereocontrolled C(sp(2))-B/B '-B ' cross-metathesis with both symmetric and non-symmetric diboron reagents.

Automated summary

The exchange of boryl moieties between alkenylboranes and diboron reagents is proposed as a stereospecific cross-metathesis pathway, leading to the formation of mixed diboron reagents. Density functional theory calculations suggest a mechanism for stereocontrolled C(sp(2))-B/B'-B' cross-metathesis with both symmetric and non-symmetric diboron reagents.
