Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， name: 2,4,6-Triphenylpyrylium tetrafluoroborate, Which mentioned a new discovery about 448-61-3
Direct photolysis of enol acetates of 3-phenylpropiophenones 1a-c gives rise to the parent propiophenones 2a-c and the 1,3-acyl shift products 3a-c.By contrast, 2,4,6-triphenylpyrylium tetrafluoroborate sensitized photolysis of substrates 1a-c affords the alpha-acetyloxypropiophenones 7a-c as the most general products.These results have been rationalized according to the generation of radical pairs in the direct photolysis and radical cations in the photoinduced electron transfer processes. Keywords.Enol acetates of 3-phenylpropiophenones; 1,3-Acyl migration; Photoinduced electron transfer; 2,4,6-triphenylpyrylium tetrafluoroborate.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, name: 2,4,6-Triphenylpyrylium tetrafluoroborate, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 448-61-3
