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(sp2)–B/B′–B′ cross-metathesis with both symmetric and non-symmetric diboron reagents.

硼烷和二硼试剂之间
硼基部分的交换已被假定为一种立体特异性交叉复分解途径,伴随着混合二硼试剂的形成。DFT 计算提出了立体控制的 C(sp 2 )–B/B'–B' 交叉复分解与对称和非对称二硼试剂的机制。
