The synthesis and properties of tris(3,3‐dimethyl‐1‐butynyl)borane ( 1 ), the first donor‐free tris(alkynyl)borane, and of its adducts 2 [donor = pyridine ( 2a ), triphenylphosphane ( 2b ), tetrahydrofuran ( 2c )] are reported. X‐ray structure analyses reveal that the B−C bond lengths in 1 are shorter than in 2 ; however, the C≡C triple bond lengths are similar to those of the donor‐stabilized compounds 2a , 2b , and 2c .
