ABSTRACT: In the title compound, C(41)H(64)B(2)O(4), one of the five-membered rings has an envelope conformation, while the other, which may be affected by disorder, is nearly coplanar with the fluorene ring. The dihedral angle between the fluorene and dioxaborolane rings is 2.29 (1)°. Two of the methyl groups are disordered over two orientations in 0.67 (3):0.33 (3) and 0.568 (10):0.432 (10) ratios.Acta Crystallographica Section E Structure Reports Online 12/2011; 67(Pt 12):o3449. · 0.35 Impact Factor
