Usage

General Description

Fluorescent brightener 185, also known as FB 185 or FBA 185, is a chemical compound that belongs to the category of stilbenes. This specific chemical substance is frequently used in detergents and washing powders to enhance whitening effects. It works by absorbing invisible ultraviolet light and emitting it as visible blue light, thereby making treated materials appear whiter and brighter. Continuous or prolonged exposure to this chemical may cause skin and eye irritation, but overall, the risks associated with it are considered to be low and it's often deemed safe for public use. Information about its impact on the environment is limited.

Stable Pd(0) Complexes with Ferrocene Bisphosphanes Bearing Phosphatrioxaadamantyl Substituents Efficiently Catalyze Selective C-H Arylation of Benzoxazoles by Aryl Chlorides

Versatile applications and unique performance of 1,1’-bis(diphenylphosphanyl)ferrocene (dppf) in coordination chemistry and catalysis prompted the search for its analogs. This contribution describes the synthesis of the first donor-unsymmetric dppf congeners bearing bulky and rigid 1,3,5,7-tetramethyl-2,4,6-trioxa-8-phosphaadamantyl (CgP) donor groups, viz. Ph2PfcPCg (1) and Ph2PfcCH2PCg (2; fc=ferrocene-1,1’-diyl). Bis-phosphanes 1 and 2 were converted into air-stable Pd(0) complexes, [Pd(ma)(L^L)] (L^L=1 and 2; ma=maleic anhydride). Together with [Pd(ma)(dppf)], these complexes were applied as catalysts in Pd-catalyzed C?H arylation of benzoxazoles with aryl chlorides in n-butanol as an environmentally benign solvent. Among all catalysts tested in this study, complex [Pd(ma)(2)] performed the best, providing a high-yield and selective synthesis of 2-arylbenzoxazoles from a range of the generally less reactive chloroarenes at low catalyst loading (typically 1 mol.%). Under similar conditions, the structurally related heterocycles (e. g., 1-methylbenzimidazole and benzothiazole) did not react.

BENZOXAZOLE DERIVATIVES AND FLUORESCENT MATERIAL COMPRISING THE SAME

The present invention relates to a benzoxazole derivative represented by structural formula 1. Accordingly, it is possible to provide a fluorescent material which has a significantly improved fluorescence yield, has excellent dyeability and dispersibility, minimizes environmental pollution by reducing the amount of use, and also can improve economic efficiency.COPYRIGHT KIPO 2020
