烯丙基硅烷1的硼氢化产生Z异构体10作为动力学产物，在与己醛缩合后产生羟基烯丙基硅烷15，而E异构体4和12在化学上更稳定，主要提供9。
Hydroboration of allenylsilanes 1 produces the Z isomers 10 as the kinetic product, leading to hydroxyallylsilanes 15 after condensation with hexanal, whereas the E isomers 4 and 12 are thermodynamically more stable, affording 9 predominantly.
