Resonance structure B is not significantly involved in the π‐etectron distribution of the deprotonated borylborataalkynes 1 , as shown by structure analysis and NMR spectroscopic data. This finding, together with the fact that the B sp C sp distance found for 1b · 2Et 2 O is in exact agreement with that calculated for HB ⊖ CH, supports the presence of a true BC triple bond in 1 , as shown in A. a , R 1 = 2,4,6‐Me 3 C 6 H 2 ; b , R 1 = 2,3,5,6‐Me 4 C 6 H; R 2 = Me 3 Si.
