چکیده
In the title compound,, [Fe(C(5)H(5))(C(17)H(20)BO(2))], the two near parallel cyclo-penta-dienyl rings of the ferrocene group are eclipsed. The benzene ring is tilted with respect to the attached cyclo-penta-diene ring by 17.0 (1)° and by 24.2 (1)° with respect to the dioxaborolane ring. The mol-ecules assemble in the crystal via C-H⋯π inter-actions between the cyclo-penta-dienyl H atoms and the benzene and cyclo-penta-dienyl rings of neighbouring mol-ecules.

The complete mol-ecule of the title compound, C(28)H(28)B(2)Br(4)O(4), is generated by the application of a centre of inversion. In the mol-ecule, the BO(2) plane is perpendicular to that through the pyrene ring [dihedral angle = 86.27 (13)°]. In the crystal, mol-ecules stack into columns along the b axis, the closest contact between these being of the type C-Br⋯π.

In the title mol-ecule, C(32)H(52)B(2)O(4)S(2), the two thio-phene rings are twisted by 67.34 (2)°. In the crystal, weak C-H⋯O hydrogen bonds link mol-ecules related by translation along the a axis into chains.

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.

متن کاملOn the Reaction Mechanism of the Rhodium‐Catalyzed Arylation of Fullerene (C60) with Organoboron Compounds in the Presence of Water
Density functional theory (DFT) calculations were carried out to study the reaction mechanism of the Suzuki-Miyaura rhodium-catalyzed hydroarylation of fullerene (C60) by phenylboronic acid in the presence of water. As found experimentally, our results confirm that addition of the phenyl group and the hydrogen atom in C60 occurs at the [6,6] bond. The rate-determining step corresponds to the si...
