Application of 1806-29-7, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 1806-29-7, Name is 2,2-Biphenol, molecular formula is C12H10O2. In a Article£¬once mentioned of 1806-29-7
Preparation and Single Crystal X-Ray Diffraction Study of Some Fluorophosphites and Phosphite Esters
The synthesis of some monofluorophosphite esters from the appropriate hydroxy compound and PCl2F in the presence of a tertiary amine is described.The reaction of 2,2′-dihydroxy-biphenyl with PCl3 in the presence of triethylamine did not furnish the expected chlorophosphite 9; instead, the bridged biphosphite ester, 10, was obtained.Reaction of the fluorophosphite ester 8 with 3,5-di-tert-butyl-benzoquinone furnished the spiromonofluorophosphorane 12 in which lambda5P is part of a five-membered and a seven-membered ring system.Single crystal X-ray diffraction studies were conducted on compounds 2, 10 and 13.In the case of 2, crystallographic 2/m symmetry and short intermolecular P…O distances were observed.Compound 10 shows short intramolecular P…O contacts.The catechyl phosphate 13, similarly to other dialkylphosphate esters, was found to be a hydrogen-bonded dimer.Key Words: Dichlorofluorophosphine, Fluorophosphites, Bridged Phosphite, X-Ray
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1806-29-7 is helpful to your research., Application of 1806-29-7
