Anion- and Solvent-Induced Single-Crystal-to-Single-Crystal Transformation within an Iron(II) Triazole System: A Promising Luminescent Probe for CrO42- and Cyano-Containing Molecules

Anion- and solvent-induced single-crystal-to-single-crystal transformation within an iron(II) triazole system has been generated from {[Fe(TPPT)2Cl2]·CHCl3}n (1a) to [Fe(TPPT)(C2O4)0.5Cl(H2O)]n (1b). Luminescence studies indicated that the resultant 1b can be considered as a promising luminescent probe for CrO42- and cyano molecules.

Brominated Diphenyl Ethers - an Important Step on the Way to Synthetic Lubricants

Preparation method of 4-phenoxy phenylboronic acid

The invention discloses a preparation method of 4-phenoxy phenylboronic acid, which belongs to the technical field of organic boric acid chemistry. The preparation method comprises the following steps: starting from diphenyl ether, reacting with NBS to generate 4,4'-dibromo diphenyl ether, reacting with borate and butyl lithium by a one-pot method, and hydrolyzing to obtain 4-phenoxy phenylboronicacid. According to the method, dibromides which are easy to purify are generated during bromination, monosubstituted products are generated by controlling the using amount of a lithiation reagent andthe boric acid ester during lithiation, the method is verified on the scale of 100 kg, and the method has the prospect of industrial methods.
