Tetracoordinate　boron　compounds　are　a　highly　important　class　of　molecules,　which　are　the　key　intermediates　in　many　organoboron-related　chemical　transformations　and　have　unique　luminescence　properties.　However,　the　synthesis　of　tetracoordinate　boron　compounds　has　never　been　reviewed.　In　this　highlight,　we　summarize　recent　progress　on　the　construction　of　racemic　and　chiral　tetracoordinate　borons,　and　hope　to　provide　ideas　for　the　assembly　of　them　in　more　efficient　ways,　especially　for　the　construction　of　boron-stereogenic　compounds.　©　2023　The　Royal　Society　of　Chemistry.
