Boron-Targeted H-Atom Transfer Drives Disproportionation of 2,1-Benzazaborolyl Radical Anions Beyond Reversible Gomberg-Krause Dimerization

This contribution provides a detailed mechanistic insight into a remarkably complex reaction of neutral 1-Ph-2- tert -butyl-1 H -1,2-benzazaborole ( 1 ) with elemental potassium in THF, yielding the known 10π-aromatic 1 H -2,1-benzazaborolyl ( 2,1-Bab − ) potassium salt ( 2 ),...
