An ethene analogue with a BB bond and two negatively charged boron centers ( 2 ) is formed from the reduction of 1 with lithium powder to 2 ‐2 Li. Based on UV data, the BB bond energy is estimated at 40 kcal mol −1 . This double bond is formed at the expense of two BN bonds in 1 , as reflected in the significant lengthening of the BN bonds on transition from 1 to 2 .
