Triethylborane (TEB), also called triethylboron, is an organoborane (a compound with a B–C bond). It is a colorless pyrophoric liquid. Its chemical formula is or , abbreviated . It is soluble in organic solvents tetrahydrofuran and hexane.
==Preparation and structure== Triethylborane is prepared by the reaction of trimethyl borate with triethylaluminium: Et3Al + (MeO)3B → Et3B + (MeO)3Al The molecule is monomeric, unlike H3B and Et3Al, which tend to dimerize. It has a planar BC3 core.
