This was shown by the low activation enthalpies (≈22–23 kcal mol−1) of double 1,2-rearrangements of borylmethyleneboranes, in which alkyl groups migrate from carbon to boron and aryl groups from boron to carbon. Ab initio calculations reveal that tetramethyldiborylcarbene 2 is only 23.1 kcal mol−1 higher in energy than tetramethylborylmethyleneborane 1.
