Phosphine adducts of 1,2-dibromo-1,2-dimesityldiborane(4): Between bridging halides and rearrangement processes

To bridge or not to bridge depends on the size of the Lewis base in mixed sp2-sp3 phosphine adducts of Br2B 2Mes2. Whereas reaction with bulky PMeCy2 induced a 1,2-rearrangement to afford the 1,1-dimesityl adduct as the major component, the normal 1,2-dimesityl adduct was favored for the smaller PEt3 molecule. The latter contains an uncommon B-Br-B bridge and a rare dative B-Hal bonding interaction to the sp2 boron center. Copyright
