Flat, tri-coordinate boron rears its had, becomes tetra-coordinate and chiral! When treated in an appropriate manner, it forms enantiomers that are configurationally stable. Only since recently, boron-stereogenic complexes are accessible by catalytic enantioselective syntheses. What makes this particularly exciting is that tetra-coordinate boron compounds are considered promising light-emitting materials.

硼基对映异构体

扁平的三配位硼恢复原来的状态，变成四配位和手性！当以适当的方式处理时，它会形成构型稳定的对映体。直到最近，硼立体络合物才可以通过催化对映选择性合成来获得。特别令人兴奋的是四配位硼化合物被认为是有前途的发光材料。
