Study On The Chemical Ransformation Of Fluorine-containing Compounds,the Weak Interactions Of Organofluorine Compounds And The Preparation Of Photoinitiator

The thesis consists of two parts:1)the chemical ransformation of fluorine-containing compounds and the study of the weak intramolecular and intermolecular interactions of organofluorine compounds.2)the preparation of 1-hydroxy-eyelohexyl-Phenyl-Ketone photoinitiator.Part 1.The reactions of multi-substituted fluorine-containing a,?-unsaturated ketones and electron-rich olefins were studied in detail.these multi-substituted fluorine-containing a,?-unsaturated ketones are elerion-poor 1-oxa-1,3-butadienes.They counld be used to afford multi-subsituted dihydropyrans in quantitative yield and mild conditions.Four crystals 11,12,13,14 were formed from the reaction of 4-nitro-2,3,5,6-tetrafluorophenol with N,N-dimethyl aniline,N,N-dimethyl-4-aminopyridine,3-aminopyridine and 4-aminopyridine.the weak intramolecular and intermolecular interactions such as hydrogen,weak F··F and p-p stacking are all influence factor in the self-assembling of these different crystals.Part 2.The study on the preparation of 1-hydroxy-eyelohexyl-Phenyl-Ketone photoinitiator.We have developed a new and cost-effective method for the synthetize of this Polymer photoinitiator.The new methed was a preferred method with industrial prospect.
