Paragraph 0031; 0038-0040, (2021/06/13)
The invention discloses a preparation method of tetraphenylborate. Sodium tetraphenylborate reacts with a quaternary salt compound under the synergistic effect of water and an organic solvent to prepare a tetraphenylborate product, and the organic solvent is an organic solution which can dissolve the quaternary salt compound and does not participate in the reaction. According to the method, the process of almost quantitatively reacting sodium tetraphenylborate with the quaternary salt compound in a mixed reaction system consisting of water and an organic solution to obtain an organic quaternary tetraphenylborate product is realized, the product purity is high, and the byproduct sodium salt is completely dissolved in water, so that interference byproducts are avoided, the method is suitable for efficient and high-purity large-scale preparation and production of organic tetraphenylborate.

Size matters: The strategy of divergent dendronization allows for the synthesis of unprecedented large, rigid, and bulky anions (see picture). Their size, density, and chemical nature of surface can be tailored to obtain more hydrophobic, less nucleophilic, and more weakly coordinating anions. Copyright

Halosubphthalocyaninatoboron, [B(X)spc] (X = F, Cl, Br) is obtained by heating phthalonitrile with boron trihalide in quinoline (X = F) or the corresponding halobenzene, resp. [B(C6H5)spc] is prepared from phthalonitrile and tetraphenylborate or tetraphenyloboron oxide, resp. [B(OR)spc] (R = H, CH(CH3)2, C(CH3)3, C6H5) is synthesized by bromide substitution of [B(Br)spc] in pyridine/ HOR. Substitution of [B(Br)spc] in carboxylic acids yields [B(OOCR)spc] (R = H, CX3 (X = H, Cl, F), CH2X (X = Cl, C6H5), C6H5). All subphthalocyaninates are characterized electrochemically and by UV-VIS, IR/FIR, resonance Raman, and 1H/10B-NMR spectroscopy. Typical B-X stretching vibrations are at 622 (X = Br), 950 (Cl), 1063 (F), 1096 cm-1 (OH) as well as between 1119 and 1052 cm-1 (OR) resp. 985 and 1028cm-1 (OOCR). The difference v(C=O)-v(C-O) > 400 cm-1 confirms the unidentate coordination of the carboxylato ligands. According to the crystal structure analysis of [B(OH)s,pc], [B(OH)spc] · 2H2O, [B(C6H5)spc], [B(OC(CH3)3)spc], [B(OOCCH3)spc] · 0.5H2O · C2H5OH and [B(OOCCH3)spc] · 0.4H2O · 1.1 C5H5N the spc ligand is concavely distorted. This saucer shaped conformation is independent of the acido ligands and the presence of solvate. The outermost C atomes are vertically displaced in part by more than 2 A from the N, plane. The B atom is in a distorted tetrahedral coordination geometry. It is displaced by ca 0.64 A out of the NI plane towards the acido ligand. The average B-N distance is 1.500 A, and the B-O distances range from 1.418(5) to 1.473(2) A.
